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 … WebWien’s Law, named after the German Physicist Wilhelm Wien, tells us that objects of different temperatures emit spectra that peak at different wavelengths. Hotter objects emit radiations of shorter wavelengths, and hence they appear blue. Similarly, cooler objects emit radiations of longer wavelengths, and hence they appear reddish. ipsma charleroi soins infirmiers

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.
