WebMar 14, 2024 · 4. Cosmic Microwave Background is the most perfect black body that have been observed - it has near ideal Planck spectrum at temperature of 2.7 K. Assuming the theoretical prediction that black holes emit Hawking radiation, it would also be a black body radiation, but it was never observed. WebA blackbody is an idealised emitter and absorber of radiation. It is an object that absorbs all radiation (or light) that is incident on it, i.e. it would appear black when any wavelength of light is shone on it. 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.
