WebIn the preceding radiation laws, we have been taking about the ideal amount of radiation than can be emitted by an object. This theoretical limit is called "black body radiation". However, the actual radiation emitted … WebA 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 ...

http://www.ccpo.odu.edu/SEES/ozone/class/Chap_4/4_6.htm WebThe effective temperature of a body such as a star or planet is the temperature of a black body that would emit the same total amount of electromagnetic radiation. [1] Effective temperature is often used as an estimate of a body's surface temperature when the body's emissivity curve (as a function of wavelength) is not known.
