In physics, Rayleigh-Jeans Law, first proposed in the 19th century, expresses the energy
density of blackbody
radiation of wavelength λ as
-
where λ is in meters, T is the temperature in Kelvins, and k is Boltzmann's
constant.
The law agrees with experimental measurements for long wavelengths but disagrees for short wavelengths, where it diverges and
leads to the ultraviolet catastrophe.
Max Planck revised the law, which states:
-
where h is Planck's constant, c is the speed of light.
