Questions and AnswersHere are common questions and answers relating to Sun Peaks... Snow Skiing QuestionsThere are currently no questions relating to Sun Peaks in the snow skiing category.Questions from Other CategoriesThe following questions were posted in various Yahoo's categories other than 'Snow Skiing' - hopefully they are relevant: The emission of solar radiation by the sun peaks at which wavelength?Full question:The emission of solar radiation by the sun peaks at which wavelength? Any help appreciated Best answer:A lot of the books give different answers but 504 nm is the one I always use. Its in the middle of the visible spectrum and not suprisingly our eyes are most sensitive at this wavelength. The Sun's spectrum peaks at 5600 Angstroms. At what wavelength does the spectrum of a star with half the?Full question:temperature of the sun peak? if the star is the same radius as the sun, how much fainter is it (both observed from the same distance)? Best answer:Wien's Law (which you can Google for) says that the wavelength of the peak of the radiation spectrum is inversely proportional to the absolute temperature, therefore the answer to the first part of your question is 11200 Angstroms. The second part of your question is a second question, which you should ask separately. You are bending the Google rules by trying to ask two questions for the price of one. The sun's spectrum peaks at 5600 Angstroms. At what wavelength does the spectrum of a star with half the..?Full question:temperature of the sun peak? If the star is the same radius as the sun, how much fainter is it (both observed from the same distance)? if you could show work that would be awesome because I want to know how to do it not just get the answer. Thanks Best answer:If you 1/2 the temperature, you double the wavelength. This is Wein's law λ = b/T .... Wiki: http://en.wikipedia.org/wiki/Black_body#Wien.27s_displacement_law This means that: λ = T.sun/T.star * λ.sun λ = 2 * 5280 Angstrom λ = 10,560 Angstrom Brightness? In reality, most of the new star's light signature will be in the infrared, but I'll assume you are looking at energy. Energy varies with T^4. This is the Stephan-Boltzmann law http://en.wikipedia.org/wiki/Stefan–Boltzmann_law Lum.star/Lum.sun = (T.star)^4/(T.sun)^4 Lum.star = Lum.sum (T.star/T.sun)^4 Lum.star = Lum.sun (1/2)^4 Lum.star = 1/16 Lum.sun anyone who has gone to sun peaks BC, what did you think? LOTS OF ANSWERS?Full question:soooo im going there on my march break, and im not a really good snowboarder but i still want to go, is it a good place? Best answer:Sun Peaks, BC is awesome! As a beginner you can't be in a better place because, unlike most other ski resorts, you can go to the very top of the highest mountain and slide all the way back down on a 'Green' run called 'Five Mile' which is wide and gently sloping. Sun Peaks has the 2nd largest ski terrain in BC and 3rd largest in Canada and 3 mountains so there is plenty of variety for all levels of skiers and boarders. You have to see it to believe it. Sun Peaks or Silverstar?Full question:Which is the best for big terrain, good snow, and good weather Sun Peaks or Silverstar??? Which would you do if you were going to Whistler also? Best answer:I'd choose to go to sun peaks. I find that around this time they get quite a bit of sunshine and also it's not that far from whistler. Last time i went was in the begining of December. The terrain was great and the snow was pretty good to ride on. Here's the web page for more info. http://www.sunpeaksresort.com/ Hope you have fun riding! Snowboarding SUN PEAKS?Full question:going snowboarding in sun peaks, Kamloops, B.C in March this year. Is the snow still going to stay on the mountain and is it usually open around March for snowboarding? Best answer:Sun Peaks closes in April. There is usually lots of snow in March. Snow history, from the Sun Peaks site http://www.sunpeaksresort.com/weather-and-cams/snow-history I have just spent a couple of weeks there. You will have a great time. Have you been to Sun Peaks Resort, BC?Full question:I'm going skiing in Sun Peaks this January, and wondered if anyone could give me a first hand account/review? I'm staying at the Delta Sun Peaks, so any info/advice on that would be great. But more importantly...where's the best skiing? and the best places to eat and drink? I understand Sun Peaks doesn't have massive nightlife, that that's fine for me, but good restaurants? Bars? THis is my first time skiing in Canada; I can't wait! Best answer:Hello I own a home up at sun peaks and I go there during the winter. The delta is by far the nicest hotel there(I used to stay there). First of all when you check in ask if you can have your room in the residences. This is a new section of the Delta and it is very nice. The pools there are nice and The Mantles restaurant serves good food at a reasonable price. I would highly recommend it. Definitely go there for a continental buffet breakfast in the morning. Next, for skiing, if you do not know the mountain and would like to get a nice view and ski day. Take a Sun Guide tour. You can ask about them at the Delta front desk. Their tours are free and come in three different levels, depending on your ability. On most days Olympic ski champion Nancy Green will be skiing. You can go ski with her for free in a group. On sunny days definitely go to the Crystal it is gorgeous and great skiing. Plus, you can see for hundreds of kilo meters. Good places to eat and drink. Well for breakfast, go across the street to Bags sweets. They make excellent crepes and are very friendly. For lunch you can hit bentos for some good cafeteria food or you can go to the top of the Sunburst for some classic Canadian food. The restraint is cheap and the food tastes amazing. Make sure to order a Cinnamon bun while up there or else you will miss the best food at sun peaks. For dinner you could hit up mountain high pizza for some tasty canadian pizza, mantles for some quality food or Fox And Hounds for some multi cultural foods and cuisine. Later you could visit the newly installed Max's nightclub for some grooving. My friend owns it and it has been a huge success. If your into chocolate then be sure to visit the rocky mountain chocolate factory. If you have any other questions or would like more info email me. Oh and if you were considering Going to the nightclub, I might Be able to get you in. Be sure to use the deltas ski valet to keep your equipment and heat your boots. If it is you first time skiing the bunny hill is open from 830 to 700 so you can get a full day in. Let me know how your trip went after. Oh and one last thing the sun dance is a majority of blue runs or fairly easy ones. Check the grooming daily too so you ski only the freshest runs. Whislter Trip - Should we also go to Sun Peaks or Big White also?Full question:We have been snowboarding at whislter twice this year and are going again in a few weeks and will stay there for about 2 weeks. Would you shorten that a few days and also go to another place also = SunPeaks or Big White. We love the big alpine areas and all the choices while boarding whistler. Is it worth going to one of these other places for a few days? Which would you go to if so Sun Peaks or Big White??? Or just stay in Whistler? Or would you just spend that money on a catskiing day while in whistler and relax there and keep the stay longer there? Is the so called dry powder at sunpeaks or bigwhiteout worth the the travel to from whistler or the negatives of worse bad visibality and smaller terrain etc..??? Is it worth going to one of these other two places or just stay in whislter the entire time again (we still have not been over every inch of it)? It would be fun to experience a little of something different. If so which is best??? Thanks Best answer:I wouldn't bother with Big White, but Sun Peaks is fun. There can be a problem going from a big resort to a small resort - I would go to Sun Peaks first, although you will be going from good snow to slightly less good snow. What excites you most - snow quality or terrain? If terrain, do Sun Peaks first. If snow quality, do Whistler first. The Sun has a temperature of 5800 , and its blackbody emission peaks at a wavelength of approximately 500 .?Full question:The Sun has a temperature of 5800 , and its blackbody emission peaks at a wavelength of approximately 500 .nm At what wavelength does a protostar with a temperature of 1900 radiate most strongly? temperature in K Best answer:Apply Wiens Law; that relates the temperature of an object to the maximum wavelength at which the object emits the most radiation. The application of Wiens Law enables us to simply look at a stars' or planets' spectrum and in determining at what wavelength it peaks at, estimate the stars' or planets' temperature. According to Wiens Law: The wavelength of peak emission is inversely proportional to the temperature. Mathematically, λ(max) = 0.29 cm/T = 0.29/1900 = 1520 nm where: 0.29 cm is the experimentally-determined proportionality constant. Hope this helps! The Sun has a temperature of 5800 K, and its blackbody emission peaks at a wavelength of approximately 500 nm?Full question:At what wavelength does a protostar with a temperature of 1500 K radiate most strongly? Please help me. Thanks. :) Best answer:Yes. Use Wien's displacement law. wavelength = b/temperature .b = 3 * 10^-3 but you dont need that since wavelength is inversely proportional to temperature for a black body. so .. 5800 --> 1/500 nm^-1 as 1500 --> 1/x cross multiply and find x 5800/1500 = x/500 find x ;) Compared to the Sun, a star whose spectrum peaks in the infrared is: ?Full question:Compared to the Sun, a star whose spectrum peaks in the infrared is: 1. cooler 2. hotter 3. larger Best answer:Infrared is lower energy (therefore cooler) than visible light. Why is it colder high up in the mountains although the peaks of the mountains are nearer to the sun?Full question:
Best answer:i think this website will tell you what you want Does anyone know where this is from - A glorious golden yellow sun peaked over crystal white glaciers throwin?Full question:Does anyone know which book or poem this is from:- A glorious golden yellow sun peaked over crystal white glaciers throwing illuminous colours over the snow and sky. A bright new morning approached, one that would end what seems like a lifetime of eternal darkness. Best answer:Eldest? When sun PEAKS in 2012, will people admit that global warming is caused by the sun?Full question:When the Earth starts to cool after the sun passes its maximum in solar variation, will the liberals admit they were wrong? Or will they hope nobody notices? http://www.futurepundit.com/archives/002242.html http://www.smh.com.au/articles/2004/08/01/1091298577537.html http://news.bbc.co.uk/2/hi/science/nature/3869753.stm http://www.space.com/scienceastronomy/sun_output_030320.html http://www.eurekalert.org/pub_releases/2007-11/uoca-ssr111307.php http://www.co2science.org/scripts/CO2ScienceB2C/articles/V10/N25/C1.jsp http://www.associatedcontent.com/article/64394/solar_storm_brewing.html http://www.nasa.gov/centers/goddard/news/topstory/2006/solar_cycle.html http://www.freerepublic.com/focus/f-chat/1775189/posts http://www.agu.org/pubs/crossref/2007/2006GL028764.shtml Best answer:I'm sorry but I really think you need to read those links a little more carefully. They're great for showing that humans are causing global warming, not so good if you're trying to refute it. The first one is a look at historical changes in sunspot activity and it's relationship to global warming and cooling. It's a well documented fact the solare and terrestrail cycles have caused warming and cooling in the past. The only reference to anything 'modern' in that article states "The sun's brightness hasn't changed much over the last 20 years", if that's the case (which it is, although what the article doesn't say is that the change, all be it a small one, is a downward one) then why have temperatures increased faster in the last 20 years that at any time in known history. The second article states "It means that the very rapid rise in temperatures over the past two to three decades has definitely not been caused by the sun, but rather by other causes, primarily man-made greenhouse gases" The thrid one states "Over the past 20 years, however, the number of sunspots has remained roughly constant, yet the average temperature of the Earth has continued to increase. This is put down to a human-produced greenhouse effect caused by the combustion of fossil fuels." I didn't look at the others but I'm sure they're the same (apart from CO2 Science which is well known for publishing what they're told to publish by a certain major oil corporation). - - - - - - - - - - - A recent paper by Lockwood and Frohlich published in the proceedings of the Royal Society examines the evidence that the Sun is responsible for recent global warming. Those who advocate such theories have proposed several mechanisms for this to take place. One proposal is that the Sun simply got hotter, i.e., that the total energy output of the Sun ('total solar irradiance' or TSI) increased. Another proposal is that an increase in ultraviolet (UV) radiation from the Sun has caused changes in high-altitude atmospheric chemistry, leading to changes in the lower atmosphere and hence to changes in climate. Yet another proposal suggests that changes in the Sun’s magnetic field have blocked cosmic rays from striking Earth and thus preventing the seeding of clouds by cosmic rays, and warming our planet in consequence. All these changes are associated with changes in magnetic field strength, therefore with the cosmic rays incident on the Earth. Also, satellites have directly measured total solar irradiance (TSI) for decades. Hence if some trend in TSI, or solar UV, or cosmic rays, were the root cause of modern global warming, we’ll be able to detect a trend in measurements of TSI or cosmic rays. If TSI is going up and/or solar magnetic field strength is going up and/or cosmic rays are going down, that would make the solar-cause more plausible. If not, then solar changes simply can’t be the cause of recent global warming. Finding the trend in these variables is complicated by the fact that in addition to getting higher or lower, they oscillate up and down with the solar cycle. The Sun has a roughly 11-year cycle, during which the sunspot count goes up and down, as do TSI and magnetic field strength. Because of the change in magnetic field strength, the count of cosmic rays striking Earth fluctuates on this same cycle. Here are the measurements of sunspot counts (figure1 - R), solar magnetic field (figure 2 - Fs), cosmic ray counts (figure 3 - C), total solar irradiance (figure 4 - TSI), and Earth’s global temperature anomaly (figure 5 - ∆) for about the last 30 years. Figures 1 to 5 (from Lockwood and Frohlich) - http://profend.com/temporary/lw1.jpg To determine the trend, we must remove the cyclic influence, leaving only the secular change: the trend. Lockwood & Frohlich used a novel, and (in my professional opinion) very robust and reliable method, to do so. They determined these trends: Figures 6 to 11 (from Lockwood and Frohlich) - http://profend.com/temporary/lw2.jpg Clearly solar activity was on the increase, as indicated by increased sunspot counts, increased solar magnetic field strength, decreased cosmic ray counts, and increase TSI, UNTIL about 1985. Since then, sunspot count is down, solar magnetic field strength is down, cosmic ray counts are up, and TSI is down. Every one of these factors would tend to cool Earth’s climate. But Earth’s temperature (according to both GISS and HadCRU) has kept going up. None of the proposed solar influences, which would warm the Earth, is going in the right direction to do so. In fact, over the last 30 years none of them has gone in a single direction; they’ve all gone up then down, or down then up. But Earth’s temperature has marched inexorably higher. It’s called global warming. The result is crystal-clear: it’s not the Sun. Anyone ski/snowboard at Sun Peaks in Kamloops, BC?Full question:Just For Fun Question Best answer:Yes, but this winter I am going to Jackson Hole. snowboarding trip Sun Peaks or Big White?Full question:
Best answer:Hi, I am a groomer from Sun Peaks and I choose my own hill. If you are an experienced boarder head for the Burfield side and ride the mid or Crystal chairs. Avoid the Westbowl and the Sundance. Morissey is okay for trees. I'm not a park rider but I built stuff in there and I guess it is okay. I have never seen Big White's park. Nothing beats the old Lake Louse park though. Before patrol made it no fun. Damn old patrollers and their old skier ways. Anyway at least Sun Peaks doesn't have the flat light problems as bad because it is more in the trees. See you there this winter hopefully! Ur flying east and the sun is rising on the horizon, how fast must one fly to keep the sun "rising"?Full question:If you were flying East in an aircraft toward a rising sun (peaking over the horizon), how fast would you have to travel in order to keep the appearance of the sun in the eastern horizon (due to the curvature of the earth). Meaning, the sun does not move from the eastern horizon or pass over you while travelling. Best answer:__________________________________ Radius of earth = r =6.378*10^6 m Time period of earth = T =24 hours =24*3600 second Time period of earth = T =86400 s Linear velocity (v) =radius(r)*angular velocity(w) angular velocity(w)=2(pi) /time period(T) v =r*2(pi)/T v =6.378*10^6*2*3.1416 /86400 v =463.82 m/s or 1669.76 km/h In order to keep the appearance of the sun in the eastern horizon, you have to travel with a speed of 463.82 m/s or 1669.76 km/h( ,Mach - 1.34 , more than speed of sound) ___________________________________ The Sun has a temperature of 5800 {\rm K}, and its blackbody emission peaks at a wavelength of approximately 5?Full question:At what wavelength does a protostar with a temperature of 1500 K radiate most strongly? Best answer:Your units are confused. what is {\rm K} supposed to mean? Wavelength of 5 what? . compared to the Sun, a star whose spectrum peaks in the infared is .... cooler,hotter, or larger?Full question:
Best answer:This is actually not related to size whatsoever, so you can rule out that option. Our sun's spectrum peaks between the yellow and the green. Red is the weakest type of light, Violet/Ultra-Violet is the strongest (infrared is in the red section). Yellow and green are mostly in the center (scientists have proved indigo is actually not part of the spectrum). Between yellow and green is dead center, so: Our sun has a medium heat intensity. A star with a red spectral peak would have a minimal heat intensity, second to which would be orange, and then afterward pure yellow. Pure green, blue, and violet are all hotter than ours. A star with a red spectral peak would be cooler than ours. A star whose thermal spectrum peaks in the infrared must be cooler than our Sun?Full question:true or false? Best answer:true Why is the Sun not the same color as its peak emission frequency?Full question:If I am not mistaken, the Sun has it's peak emission frequency in the green wavelength. Best answer:Well, why do most people think the sun appears yellow when it doesn't? The sun appears white to the naked eye. (Which would be more obvious if you could actually stare at it long enough.) That doesn't mean that there aren't stars which display a definite color...and contrary to the previous answer, there are green stars--one being in the multiple system of Gamma Andromeda. What is the minimum amount of time in the sun where you should use sunscreen?Full question:obviously, one wouldn't wear sunscreen to be outside for 2 minutes and equally obviously you should certainly wear sunscreen to sit on the beach for 2 hours. so whats the actual minimum amount of time in the sun which requires sunscreen? whats the minimum time in the sun that could cause sunburn? assume it's a clear, cloud free sky with direct sun during the peak hours. please provide as specific a number of minutes as possible, not vague recommendations about general sunscreen usage magidge, its clearly not zero minutes. Best answer:It would depend on the temperature. Usually the minimum amount of time in the sun without sun screen would be zero time, unless of course you want to end up with wrinkled hard skin when you get older, or even worse a skin condition which could be dangerous! Oviously it would also depend on your skin type. Spectograph, star and sun temperatures problem?Full question:The thermal spectrum emitted by the Sun peaks right in the middle of the visible portion of the electromagnetic spectrum. You use your trusty spectrograph to measure the thermal spectrum from another star, and find that it peaks at a wavelength that is 5.34 times the peak wavelength of the Sun's spectrum. What is the ratio of the surface temperature of that star to the surface temperature of the Sun? Best answer:http://www.astro.umd.edu/educationalresources/astro/sprop/wien.html has: Wien's law: aT=30,000,000 where a is angstroms, T is Kelvin degrees also, 30,000,000=a'T' where sun's temp is T star's temp is T' sun's peak is at a star's peak is at a' then aT=a'T' then if a' = 5.34a, solving for T'/T, aT=5.34aT' T=5.34T', T/T'=5.34 T'/T=0.187 and is probably an infrared source Is it less likely to rain at peak sun hours?Full question:When the sun is at it's peak during the day, say around noon, is it less likely to rain or even snow? I should elaborate further. Does the sun heat up the clouds, making it harder for them to condense? Best answer:Mid afternoon is the time of day that you are most likely to have a pop up shower or thunderstorm (called convective showers/storms) due to the daytime heating. The sun heats the surface, the air is forced to rise, and when air rises, it expands, cools, and condenses. From there you get cloud formation, and if the air is unstable enough (as well as other factors), vertical motion is enhanced, and you have larger, cumulus congestus clouds forming. The precipitation process goes on from there, but you now have a basic explanation how the sun helps form convective precip rather than inhibiting it. A star whose spectrum peaks in the infrared is (a) cooler than our Sun (b) hotter than our sun (c) lager than?Full question:our Sun (b) hotter than our Sun (c) larger than our Sun. Best answer:a) Cooler then the Sun. Note: C is also possible but not the answer since not all stars cooler then the Sun are larger then the Sun. How do I use Wien's law to determine the peak of the black body curve of the sun with a given temperature?Full question:Use Wien's law to determine the wavelength corresponding to the peak of the blackbody curve in the core of the Sun, where the temperature is 10^7 K? Best answer:Wein's law is a function (an equation) where (if you use the correct units) you input the temperature, and the function outputs a wavelength. L(T) = 0.0028978 m K/ T where L is the wavelength (in metres, the way it is written here) T is the temperature in Kelvin m means metre and K means Kelvin L(10^7) = 0.0028978 m K / 10,000,000 K The K cancel out, leaving you with m as the only unit and a very small number. Something like 2.9x10^-10 m These days, we express wavelength of light as nm (nanometres = 10^-9 m), so you'll be left with something close to L=0.3 nm -- somewhere near the hard X-rays. Sometimes the solar images appear smooth and featureless. What does this tell us about the Sun?Full question:a. The Sun is at a peak of magnetic activity. b. The Sun’s magnetic activity is at a very low level. c. The imaging systems are not working. d. The solar corona is too thick for photospheric details to show. Best answer:b. The Sun’s magnetic activity is at a very low level. Using Wien's Law find the peak wavelength of sunlight in nm of our Sun. What color does this correspond to?Full question:Recall that the Sun presently has a surface temperature (T)sun = 5800K , Using Wien’s law, calculate the peak wavelength of sunlight, in nm. Roughly what color does this correspond to? Best answer:Wien's Law is λ(max) = b / T where T is the temperature and b is Wien's displacement constant = 2,897,769 nm·K λ(max) = 2,897,769 / 5800 nm = 500 nm 500nm is now generally considered to be in the green part of the spectrum. It is at the blue end of green. I would call it cyan or aqua. You judge. The reference site contains picture of the spectrum with a wavelength scale. what is the minimum amount of time in the sun where you should use sunscreen?Full question:obviously, one wouldn't wear sunscreen to be outside for 2 minutes and equally obviously you should certainly wear sunscreen to sit on the beach for 2 hours. so whats the actual minimum amount of time in the sun which requires sunscreen? whats the minimum time in the sun that could cause sunburn? assume it's a clear, cloud free sky with direct sun during the peak hours. please provide as specific a number of minutes as possible, not vague recommendations about general sunscreen usage Best answer:I once went on one of those boat tours in a French city and it was summer, and the boat had no roof because they had taken it off, so I pretty much just sat there in the sun for 1h and got quite a sunburn on my shoulders...I dunno if you've noticed, but when you're out in the sun, certain body parts will start stinging after just a few minutes...I would recommend that if you're out in the sun for more than 15-20 mins, you should definitely use sunscreen. Just an educated guess though. Since mountain peaks are closer to the sun than sea level, how come the peaks are colder than the sea level? ?Full question:
Best answer:your question about how the atmosphere is heated is a good one, because the correct answer is not quickly apparent... You would surmise, that since the sun is the source of the heat for the earth and atmosphere, that the atmosphere should be warmer at points closer to the sun, like at the TOP of the atmosphere, instead of the reverse. But the atmosphere is not warmed directly by the sun...it is warmed by the EARTH...! Most of the energy from the sun arrives at the earth in the form of light energy, or short-wave energy. The atmosphere is transparent to short-wave energy, and most of the solar energy reaches the surface of the earth, where it is absorbed. This energy warms the surface of the earth, which, in turn, warms the atmosphere with long-wave energy. The type of energy radiated by a star primarily depends on the temperature. So the energy from the sun arrives at the earth as short-wave (in the visible part of the spectrum) energy, and leaves the earth as long-wave (in the infra-red part of the spectrum) energy. The atmosphere is not transparent to long-wave radiation, and absorbs the heat energy from the earth. That part of the atmosphere closest to the earth gets the most energy and is the warmest. Because the sun is nearly overhead in the latitudes nearest the equator, those locations receive more solar energy per unit area, and become warmer than those locations near the poles. This difference in the amount of energy received and subsequent heating of the atmosphere and evaporation of water from the lakes and oceans, is what drives the "weather machine" on the earth.
