WebFor electromagnetic radiation, there are four "laws" that describe the type and amount of energy being emitted by an object. In science, a law is used to describe a body of observations. At the time the law is established, no … WebStefan’s Law Wien’s Displacement Law Rayleigh - Jeans Law. Energy is not emitted or radiated continuously, It is emitted in small proportions in the form of energy packets called quanta (Photon). The energy of a photon or one quanta of energy is directly proportional to the frequency of the radiation.
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.

WebThe Rayleigh-Jeans radiation law follows from the equipartition theorem of statistical mechanics, i.e., inserting E = kT into Equ. 3. Now, many textbooks suggest that Planck somewhat extrapolated between the Wien and the Rayleigh-Jeans radiation law.
