It is … WebThis is known as the Rayleigh—Jeans 6 approximation.It says that in the microwave portion of the spectrum, radiance is simply proportional to temperature. In fact, in the microwave region, it is customary to divide radiance values by (c 1 /c 2)λ −4 and to refer to the quotient as brightness temperature.Brightness temperature is also used in the infrared portion of …
WebRayleigh–Gans approximation, also known as Rayleigh–Gans–Debye approximation and Rayleigh–Gans–Born approximation, is an approximate solution to light scattering by optically soft particles. Optical softness implies that the relative refractive index of particle is close to that of the surrounding medium.

WebRayleigh-Jeans Law. A classical law approximately describing the intensity of radiation emitted by a blackbody, derived by Rayleigh and Jeans by counting the number of standing wave modes in an enclosure. It corresponds to the Planck law in the case of small frequencies, in which case allows the approximation. (1)
