Question

explain black body radiation

Answer 1

An object that absorbs all radiation falling on it, at all wavelengths, is called a black body. When a black body is at a uniform temperature, its emission has a characteristic frequency distribution that depends on the temperature. Its emission is called black-body radiation.

Answer 2

Black body radiation is the thermal electronic radiation within or surrounding a body in thermodynamic equilibrium with its environment or emitted by a black body.
