Stefan–Boltzmann constantThe Stefan–Boltzmann constant, σ, is derived from other known physical constants: where k is the Boltzmann constant, the h is the Planck constant, and c is the speed of light in vacuum.
As of the … See moreExamplesWith his law, Stefan also determined the temperature of the Sun's surface. He inferred from the data of Jacques-Louis Soret (1827–1890) that the energy flux density from the Sun is 29 times greater than the en… See more
