Rayleigh - jeans law

WebRayleigh's scattering law. The amount of scattering is inversely proportional to the fourth power of the wavelength. This is known as Rayleigh scattering. As sunlight travels through the earths atmosphere, it gets scattered by the atmospheric particles. Light of shorter wavelengths is scattered much more than light of longer wavelengths. Web4.B] Deduce Rayleigh-Jeans law from Planck’s Law of radiation. Answer:-Reduction of Planck’s law. Planck’s law could be reduced to Wien’s distribution law and Rayleigh-Jeans law in the shorter and longer wavelength regions respectively. Thus Plack’s law explains the distribution of energy in the blackbody radiation spectrum completely.
