WebSep 9, 2024 · @Pieter No, what I mean is that the derivation of Planck's law always involves photons in a box (a photon gas) to find density of states, energy etc. I just don't understand why we do that. How does a photon gas have anything to do with a blackbody emitting radiation? – User3141 Sep 8, 2024 at 20:33 Webthe derivation of the Planck spectrum. The Stefan-Boltzmann law. 10.1 Introduction In the flrst lecture, we stated that the energy den-sity of radiation per unit frequency interval …
WebThe value of Tmax ∼ 1032 K −1/2 is exorbitantly large to be of any use, or so it seemed at least for a long time. Ten years after Sakharov’s result, Hawking derived semi-classically the temperature-mass (M) relation for the evaporation of black holes, T = 1/(8πGN M) = m2Pl /(8πM), with the spectrum of black body radiation [2, 3]. WebMar 28, 2024 · Rate of Radiation from a Black Body We can convert the formula for the energy density to the intensity of the radiation by considering the conservation of energy in electrodynamics. The energy density of the electromagnetic field is given by u = 1 2(E2 + B2) Using the Maxwell equations in free space, we find

Consequently, it absorbs all colors of light … WebFeb 19, 2024 · Planck’s law of radiation describes the radiation emitted by black bodies. However, there are different forms of representation, which will be discussed in more detail in the following. These differences are mainly due to the different quantities that are considered: e.g. intensity per wavelength or the intensity per solid angle or the energy ...
