 Stefan–Boltzmann law

The Stefan–Boltzmann law describes the power radiated from a black body in terms of its temperature.Specifically, the Stefan–Boltzmann law states that the total energy radiated per unit surface area of a black body across all wavelengths per unit time formula_1 (also known as the black-body "radiant emittance") is directly proportional to the fourth power of the black body's thermodynamic temperature "T"
