WebApproximately 75% of this intensity is absorbed by the earth. Assume that the earth is a black-body radiator and a perfect sphere of radius R. This means that the absorbing cross-sectional area is aR2 and that the area that radiates black-body radiation back into space is 45 RP. Further assume that the effective emissivity of the earth is 0.656. WebBlack Body Radiation Wien Displacement Law - Introduction Thermal energy or heat energy is transferred from one object to another. This may happen due to three different possibilities.
