Document Summary
Stefan-boltzmann law: describes how much energy is emitted by an objected based upon its temperature. Wein"s law: describes the wavelength of maximum emission that an object radiates based upon its temperature. Kirchoff"s law: the efficiency of absorption at a certain wavelength of energy is exactly equal to the efficiency of emission in the same wavelength. Any object that absorbs and emits only some wavelengths of radiation. There are many selective absorbers on our planet: Snow is great at absorbing infrared radiation, but not good at absorbing visible radiation. Kirchoff"s law says that if snow is a good absorber of ir then it must be a good emitter of ir. These gases absorb infrared radiation in the atmosphere. While they are transparent to visible radiation and radiation from 8-11 m (the. Atmospheric greenhouse effect is essential to life on earth. In the past century, earth"s average temperature has risen about 1 f or 0. 6 c.
