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…

WebPlanck’s equation describes the spectral radiance quantity radiated by a black body in equilibrium at a particular wavelength. Planck’s Equation is given as – E = hv = hc λ E = h v = h c λ Where, E = Energy h = Plank constant v = frequency c … WebThe value of Planck’s constant is found to be 6.62606957 × 10−34 joule∙second, with a standard uncertainty of 0.00000029 × 10−34 joule∙second. For a blackbody at temperatures up to several hundred degrees, the majority of the radiation is in the infrared radiation region of the electromagnetic spectrum. At shrub glasses for sale

WebThere are various ways to derive Planck’s radiation law. Beside Planck’s original one (that did not fully satisfy him), different derivations were published, for instance, by Einstein13, Bose14, Pauli15, and Kramm and Herbert.16 Einstein’s derivation of Planck’s blackbody radiation law is described, for instance, in the textbooks of ...
