Blackbody definition
Webblackbody. A hypothetical body that cannot be excited to radiate by an external source of electromagnetic radiation of any frequency, direction, or state of polarization except in a negligibly small set of directions around that of the source radiation. The traditional definition of a blackbody—as one that absorbs all the radiation incident ... WebBlack Body Radiation. A black body (or blackbody) is a term used in physics to refer to an object that absorbs all incoming energy, no matter its frequency. Black bodies have no reflective power, so no radiation is reflected, and the object appears black to the eye. Black bodies can also emit radiation (called black body radiation), which is ...
