WebPlanck considered the black body radiations (in the hohlraum) to consist of linear oscillators of molecular dimensions and that the energy of a linear oscillator can assume only the discrete values Thus we see that the average energy of the oscillator is not Kt (as given by classical theory)but equal to hv/(ehv/kt-1) according to Planck’s quantum … WebDerivation of Rayleigh-Jeans law from Planck’s law For longer wavelengths, When wavelength λ is large, υ= c λ is small. Since υ is very small, ehυ/kT will be very small. Expanding ehυ/kT as power series, we have. ehυ/kT = 1+ hυ/kT + (hυ/kT)
