Electromagnetic radiation can be generated by exciting matter to higher energies, such … A black body or blackbody is an idealized physical body that absorbs all incident electromagnetic radiation, regardless of frequency or angle of incidence. The name "black body" is given because it absorbs all colors of light. A black body also emits black-body radiation. In contrast, a white body is one with a "rough surface that reflects all incident rays completely and uniformly in all directions."

WebDec 4, 2015 · *The question was prompted by a project on the greenhouse effect, so I am mainly interested in whether it is accurate to say that the energy absorbed by the atmosphere from the thermal radiation of the earth, is subsequently emitted as blackbody radiation. John Rennie's answer seems to suggest this is not the case.
