Rayleigh jeans law of blackbody radiation
WebThe meaning of RAYLEIGH-JEANS LAW is an approximation in respect to thermal radiation: the emissive power of a blackbody at absolute temperature T and at a given wavelength λ is directly proportional to T and inversely proportional to λ4. WebOne experimental phenomenon that could not be adequately explained by classical physics was blackbody radiation (Figure 1.2.1 ). Attempts to explain or calculate this spectral distribution from classical theory were complete failures. A theory developed by Rayleigh and Jeans predicted that the intensity should go to infinity at short wavelengths.
