WebThe fourth law of blackbody radiation states that the spectral distribution of the energy emitted by a blackbody is independent of its shape and size. This means that the spectral distribution of the energy emitted by a blackbody does not depend on its shape and size, only on its temperature. This law also implies that the peak of the emission ... WebAs you go higher into the atmosphere, the temperature decreases at a rate of 9.8 ºC/km (this is called the atmospheric lapse rate), and the atmosphere becomes transparent at an altitude where the temperature is 255 K (the calculated temperature of the earth without greenhouse gases!).
