WebAfter this, he was joined by Sir James Jeans in the year 1905. Initially, Lord Rayleigh claimed the λ depends on the Rayleigh - Jeans law. That was concluded on the basis of arguments made by classical physicists and various empirical facts. This law was explained more clearly in the year 1905 by both Lord Rayleigh and Sir James Jeans. WebThe wavelength at which the radiation is strongest is given by Wien’s displacement law, and the overall power emitted per unit area is given by the Stefan-Boltzmann law. Wein’s law could explain the blackbody radiation curve only for shorter wavelengths whereas Rayleigh-Jeans’ law worked well only for larger wavelengths.

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. WebThe law is derived from classical physics arguments. Lord Rayleigh first obtained the fourth-power dependence on wavelength in 1900; a more complete derivation, which included …
