Web(3) (vi) The Rayleigh-Jeans law finds that the energy density per unit frequency is given by du « v dv. In the context of this result, sketch a diagram and explain what is meant by the term "the ultraviolet catastrophere" (1+3) Previous question Next question 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 the proportionality constant, was presented by Rayleigh and Sir James Jeans in 1905. It agrees with experimental measurements for long wavelengths.
