WebIn 1900, Max Planck developed the modern theory describing the radiation field of a blackbody. At the time, there were two distinct models for blackbody radiation: the Rayleigh-Jeans law, which fit the measurements well at low frequencies, and Wien’s law, which worked well at high frequencies, but neither worked everywhere. WebBefore the Planck’s hypothesis, physicists tried to describe spectral radiance of electromagnetic radiation by classical physics. The approximation based on classical physics is known as the Rayleigh-Jeans law.. Similarly, as for Planck’s law, the Rayleigh-Jeans law gives the spectral radiance of a body as a function of frequency ν at absolute …
