"WebIn 1900, Max Planck developed the modern theory describing the radiation field of a blackbody. At the time, there were two distinct models for blackbody radiation: the Rayleigh-Jeans law, which fit the measurements well at low frequencies, and Wien’s law, which worked well at high frequencies, but neither worked everywhere.

1.1: Blackbody Radiation Cannot Be Explained Classically

WebNov 22, 2024 · The Rayleigh-Jeans theory was constructed on the notion that when the walls of an object are in thermal equilibrium, in other words, the temperature of the walls … WebOct 28, 2013 · This follows from the assumption that EM energy inside is given by the Poynting formula. H = ∫ V 1 2 ϵ 0 E 2 + 1 2 μ 0 B 2 d V. When E,B are expressed using vector potential A as superposition of mode oscillations, H turns out to be sum of quadratic terms. Then the second step is to assume that these obeys the equipartition theorem.
