WebDec 2, 2024 · This is Rayleigh Jean Law. About Rayleigh-Jean’s Law. 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. WebAccording to Rayleigh-Jeans law the energy emitted by the blackbody per unit volume in the range of wavelength from λ to λ + dλ is given by. Where k is Boltzmann constant whose value is 1.38 × 10 −23 JK −1 . Rayleigh-Jeans formula was found to explain energy distribution only in the longer wavelength region of the blackbody radiation ... simple truth laundry detergent cloth diapers
