What is black body and what are black body radiation - BYJU

WebA blackbody refers to an opaque object that emits thermal radiation. A perfect blackbody is one that absorbs all incoming light and does not reflect any. At room temperature, such an object would appear to be perfectly black (hence the term blackbody). However, if heated to a high temperature, a blackbody will begin to glow with thermal radiation. WebApr 6, 2024 · An object which absorbs all amount of radiation of any wavelength into it is known as a black body. The term black body was introduced by Gustav Kirchhoff in 1860.
