WitrynaBlackbody radiation, temperature, and thermodynamic equilibrium give a tightly coupled description of systems (atmospheres, volumes, surfaces) that obey Boltzmann statistics. They are important because of the compact descriptions of systems that they give when Boltzmann statistics apply, either approximately or nearly exactly. Fortunately, this is WitrynaBlack Body Radiation Thermal emission from a surface at various temperatures, modeled by the Planck's equation for an ideal black body.
