Rayleigh-Jeans law Guide, Meaning , Facts, Information and Description
In physics, the Rayleigh-Jeans Law, first proposed in the 19th century, expresses the energy density of blackbody radiation of wavelength λ as
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:
