An ideal black body is an imaginary perception of Gustav Kirchhoff that played a significant role in the development of quantum mechanics.

It is a perfect emitter and absorber of thermal radiations Mind map A blackbody is a rigid, closed unreal body that can absorb all electromagnetic radiation that falls on it regardless of its frequencies, but it reflects none. The surface of a blackbody is opaque. It neither transmits light nor reflects it. Hence, its absorbing and emissive powers are one An ideal black body is an imaginary perception of Gustav Kirchhoff Definition On heating, the blackbody releases all thermal electromagnetic radiation . It is blackbody radiation. It played a significant role in the development of quantum mechanics. Blackbody Affecting factors Applications Laws governing Jayam chemistry adda Planck quantum law Temperature Used in thermal imaging. Emissivity Wien displacement law Used in optical sensors. Surface area Stefan-Boltzmann law Used to provide security in burglar alarms.
