Web= Rayleigh-Jeans law. Note that Planck’s constant drops out. This is one example of the correspondence principle; as h becomes negligible compared to other quantities in the quantum mechanical law, the result approaches the classical law. At high frequency or small wavelength, u (T) → 8 h 3 c3 e-h /kT and u (T) → 8 hc 5 e-hc/ kT WebJun 8, 2014 · All the derivations of the Rayleigh-Jeans 'Law' I've seen assume that the electromagnetic radiation is enclosed in a cube. I'm trying to derive the law using less arbitrary circumstances. That is, by starting with the equation [tex]U=\int \left[ \frac{\epsilon_0}{2}E^2 + \frac{1}{2\mu_0}B^2 \right]dV,[/tex]
