Blackbody temperature formula
WebApr 10, 2024 · A black hole is a black body and follows rules of emission and absorption. The temperature of a black hole depends on the mass and how it will emit radiation … Black-body radiation has a characteristic, continuous frequency spectrum that depends only on the body's temperature, called the Planck spectrum or Planck's law. The spectrum is peaked at a characteristic frequency that shifts to higher frequencies with increasing temperature, and at room temperature most of the emission is in the infrared region of the electromagnetic spectrum. As the temp…

The first theoretical analysis resulted in the Rayleigh–Jeans formula, based on the classical hypothesis that the energies of the photons inside the blackbody could have any values from an energy continuum.
WebStefan-Boltzmann Law The thermal energy radiated by a blackbody radiator per second per unit area is proportional to the fourth power of the absolute temperature and is given by. For hot objects other than ideal radiators, the law is expressed in the form: where e is the emissivity of the object (e = 1 for ideal radiator).

With 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 energy flux density of a certain warmed metal lamella (a thin plate).
