Energy vs wavelength formula
WebHistorical development. In 1900, the British physicist Lord Rayleigh derived the λ −4 dependence of the Rayleigh–Jeans law based on classical physical arguments, relying upon the equipartition theorem.This law predicted an energy output that diverges towards infinity as wavelength approaches zero (as frequency tends to infinity).
