Blackbody Radiation
Blackbody radiation refers to the theoretical phenomenon in which an idealized object, known as a blackbody, emits and absorbs electromagnetic radiation at all wavelengths. This concept is based on the assumption that a blackbody absorbs all incident radiation that falls upon it, while also emitting radiation in accordance with the laws of thermodynamics. The spectral distribution of this radiation is described by Planck's law, which relates the intensity of the radiation to the temperature of the blackbody. Blackbody radiation plays a crucial role in understanding various physical phenomena, such as thermal radiation and the behavior of stars.
