WebJun 1, 2009 · Black-body radiation: the Rayleigh-Jeans law. In an 1889 paper on the character of the complete radiation at the given temperature, Rayleigh defines complete radiation (black-body radiation) as radiation that, in a steady state, exists in a sealed enclosure whose walls are impervious to radiation and are maintained at a given … WebMay 22, 2024 · Before the Planck’s hypothesis, physicists tried to describe spectral radiance of electromagnetic radiation by classical physics.The approximation based on classical physsics is known as the Rayleigh-Jeans law.. Similarly as for the Planck’s law, the Rayleigh-Jeans law gives the spectral radiance of a body as a function of frequency ν at …
