WebThe Rayleigh-Jeans Law was an important step in our understanding of the equilibrium radiation from a hot object, even though it turned out not to be an accurate description of … 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.

It's not very intuitive why this is the case but their derivation goes along those lines. The very important fact is that they found that the distribution of frequencies is not homogeneous and depends on the square of the frequencies, so higher frequencies are likelier than lower ...
