Black Body Radiation: Definition, Application, Graph StudySmarter

WebA black body is a perfect absorber and emitter of radiation, meaning that it absorbs all radiation that it receives and re-emits all of that radiation as well. Black, in terms of blackbody radiation, means that. All molecular motion has ceased. Increasing temperature. The color of the blackbody radiator changes as the temperature increases. 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.
