WebThe blackbody radiation problem was solved in 1900 by Max Planck. Planck used the same idea as the Rayleigh–Jeans model in the sense that he treated the electromagnetic waves between the walls inside the cavity classically, and assumed that the radiation is in equilibrium with the cavity walls. http://hyperphysics.phy-astr.gsu.edu/hbase/quantum/rayj.html WebFor a given observation point near a radiating surface, the power will be the average power from all directions, and the average gives another factor of 1/2. Having averaged over all angles, the calculated radiated power per unit wavelength is finally. More detailed development of the c/4 factor. This is the Rayleigh-Jeans formula. small heart pillow
