First of all this is a physics question, not a chemistry question. Silvery surfaces are very good at reflecting heat radiation, dark/dull surfaces attract and absorb heat radiation.

∙ 11y agoThings that are shiny when a light is shone on it. E.g. Shining a torch on metal would shine the light away. So i think metal surfaces and things like that are the best . Basically things that are bright when a light is shone on it. Hope this helped :ddd.

∙ 11y agosoft surfaces are better at reflecting thermal radiation as they could break if they received too much thermal radiation.
the threshold value at the point at which a soft surface breaks is known as it's climax point. and agrees with the equation:
(sin x/n)=6 where n is the 14th letter of the alphabet (between m and o) x is the one before y, and 6 is equals to 7.957892199*(ln[(root to the 3*10power2) of 69 factorial)
a good analogy would be a woman's vagina. they love it, when they are about to break but once they break they hate it.

Which radiation is most common on earth?
Solar radiation is the most common type of radiation on earth. The earth also emits thermal radiation from its crust as a result of decaying of uranium.
What type of radiation is in the atmosphere due to greenhouse gases?
There is no radiation (Alpha particles, Beta particles, Gamma rays) related to Greenhouse Gases. There is some conversion of lsolar energy to thermal radiation (heat)
What type of energy from the oceans is responsible for weather patterns?
Thermal
Why does dirty snow melt faster than white snow?
This is due to the principle of albedo. Snow is among the brightest natural surfaces on earth, and therefore reflects most incoming solar radiation. If the radiation is reflected, it cannot be absorbed by the surface and converted to thermal energy (heat) to raise the temperature. When you add any type of dirt and impurities to the snow, you are lowering the albedo of the snow, causing the surface to absorb more radiation and heat up. This causes the snow to melt faster.Interestingly, if the snow is covered by more than about a centimeter of dirt, it will be insulated from the sun and melt more slowly.
What type of radiation is reflected away from the earths surface?
Long-wave radiation and visible light.
between white and silver surfaces, which one is the best emitter of radiation?
The best emitter of radiation depends on the type of radiation you are referring to. Generally, when discussing thermal radiation, a "blackbody" is considered the best emitter. A blackbody is an idealized object that absorbs all incident radiation and emits radiation perfectly according to its temperature. In real-world scenarios, there is a concept called "emissivity," which quantifies how effectively an object emits thermal radiation compared to a blackbody at the same temperature. The emissivity of an object ranges between 0 and 1, with 1 being a perfect blackbody. Regarding white and silver surfaces: White surfaces: White surfaces tend to have high reflectivity and low emissivity. This means they are good at reflecting incoming radiation and do not emit thermal radiation as effectively. In terms of thermal radiation emission, they are not the best emitters. Silver surfaces: Silver surfaces also have high reflectivity but generally have higher emissivity compared to white surfaces. They emit more thermal radiation than white surfaces, but they are still not as effective emitters as a perfect blackbody. In conclusion, between white and silver surfaces, silver surfaces would be the better emitter of thermal radiation due to their higher emissivity. However, neither of them is as efficient as a blackbody emitter. Keep in mind that the exact emissivity values can vary based on the specific properties and conditions of the materials used.
