Rayleigh index
WebSep 7, 2010 · Rayleigh-Gans scattering. In a large number of important cases, the relative refractive index of particles (with respect to that of the ambient medium) is close to one. Such particles are called “optically soft,” and the corresponding approximation could be named that of optically soft particles. The known examples of optically soft ... http://plaza.ufl.edu/dwhahn/Rayleigh%20and%20Mie%20Light%20Scattering.pdf

WebThe Rayleigh ratio (R q) is defined as the relative scattering intensity or the ratio of scattered (I s) to incident (I o) light, with the strict definition requiring that the scattering intensity be summed over all space. Because of geometric limitations imposed by the practical restriction of measuring the intensity at a given angle ( q) and ... In probability theory and statistics, the Rayleigh distribution is a continuous probability distribution for nonnegative-valued random variables. Up to rescaling, it coincides with the chi distribution with two degrees of freedom. The distribution is named after Lord Rayleigh . A Rayleigh distribution is often observed when the overall magnitude of a vect…
