Rayleigh–jeans law formula

WebTo compare the Wien Law and Rayleigh–Jeans Law with the experimental black body spectrum, it is necessary to convert ρW–T (λ) defined by Equation [1-9.4] into the frequency-dependent form, ρ W-T (υ). The crucial step is the conversion of the wavelength derivative to the frequency derivative, dλ = d ( c /υ) = d ( c υ −1) = c d (υ ... Web~Lord Rayleigh and Sir James Jeans. The mathematical equation of Rayleigh-jeans law is . Here, u() is radiant energy density, is frequency, T is the temperature in kelvins, is the speed of light, K is Boltzmann constant.
