Jeans developed an equation which explained blackbody radiation at low frequencies. The equation which seemed to express blackbody radiation was built upon all the known assumptions of physics at the time.
WebBrightness temperature or radiance temperature is the temperature at which a black body in thermal equilibrium with its surroundings would have to be in order to duplicate the observed intensity of a grey body object at a frequency .

Lord Rayleigh, a British physicist, derived the λ-4 dependence of the Rayleigh-Jeans law based on empirical facts and classical physical arguments. In 1905, Rayleigh and Sir James Jeans put forth a more complete derivation that included the proportionality constant.
