Stefan-Boltzmann law

Stefan-Boltzmann law
/stef"euhn bohlts"meuhn/; Ger. /shte"fahn bawlts"mahn/, Physics.
the law stating that the total energy radiated from a blackbody is proportional to the fourth power of its absolute temperature. Also called Stefan's law of radiation.
[1895-1900; named after Josef Stefan (1835-93) and Ludwig E. Boltzmann (1844-1906), Austrian physicists, who independently formulated the law]
