Is earth a blackbody
WebElectromagnetic waves emitted by a blackbody are called blackbody radiation. Figure 6.2 A blackbody is physically realized by a small hole in the wall of a cavity radiator. The intensity I ( λ, T) of blackbody radiation depends on the wavelength λ of the emitted radiation and on the temperature T of the blackbody ( Figure 6.3 ). WebOct 13, 2016 · When called, the black body absorbs all radiation and hence appears black. So, at high temperatures the black body appears to be white (white hot) and at very low temperatures, it appears black. An example is a tungsten filament. It can be considered as an approximation to a black body.
