Blackbody radiation law
WebApr 10, 2024 · His law was one of the first important steps toward the understanding of the blackbody radiation, from which raised the quantum idea of radiation. Stefan rose from a lecturer in the subject of mathematical physics in 1858 to a professor Ordinarius of physics in 1863 and to the director of the Physical Institute in 1866, at the University of Vienna. WebA black body in thermal equilibrium (that is, at a constant temperature) emits electromagnetic black-body radiation. The radiation is emitted according to Planck's law, meaning that it has a spectrum that is determined by the temperature alone (see figure at right), not by the body's shape or composition. An ideal black body in thermal ...
