WebThe wavelength at which the radiation is strongest is given by Wien’s displacement law, and the overall power emitted per unit area is given by the Stefan-Boltzmann law. Wein’s law could explain the blackbody radiation curve only for shorter wavelengths whereas Rayleigh-Jeans’ law worked well only for larger wavelengths. WebRayleigh-jeans law: A black body in thermal equilibrium will emit radiation in all frequency ranges, and as the frequency increases, so does the energy of the radiation emission. The … WebAccording to Rayleigh Jeans radiation waves in black body can be compared to the standing waves in cubical cavity.

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. http://hyperphysics.phy-astr.gsu.edu/hbase/mod6.html
