Derive planck's law of blackbody radiation

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 Planck's law describes the unique and characteristic spectral distribution for electromagnetic radiation in thermodynamic equilibrium, when there is no net flow of matter or energy. Its physics is most easily understood by considering the radiation in a cavity with rigid opaque walls. Motion of the walls can affect the radiation. If the walls are not opaque, then the thermodynamic equilibrium is not isolated. It is of interest to explain how the thermodynamic equilibrium is attain…
