Answer / Divakar Rao
A black body is an idealized object that absorbs all incident electromagnetic radiation, regardless of the frequency or angle of incidence. It also re-emits this radiation in thermal equilibrium, following Planck's distribution law. Some key characteristics of a black body include: 1) Emission spectrum: The emitted spectrum is continuous across all frequencies, but peaks at a specific temperature known as the blackbody curve. 2) Radiation law: The total energy emitted by a black body is proportional to the fourth power of its temperature.
