WebMar 23, 2024 · Black-body radiation is an em. (quantum) field in thermal equilibrium and as such its phase-space distribution function results from "detailed balance", i.e., it's the state, where emission and absorption rates get the same. As Einstein derived already in 1917, to get the correct Planck radiation law you need spontaneous and induced emission ... WebFormally, Wien's displacement law states that the spectral radiance of black-body radiation per unit wavelength, peaks at the wavelength λpeak given by: where T is the absolute temperature and b is a constant of proportionality called Wien's displacement constant, equal to 2.897 771 955... × 10−3 m⋅K, [1] [2] or b ≈ 2898 μm⋅K.
