Reflectivity refractive index

The refractive index and extinction coefficient, n and κ, are typically measured from quantities that depend on them, such as reflectance, R, or transmittance, T, or ellipsometric parameters, ψ and δ. See more In optics, the refractive index (or refraction index) of an optical medium is a dimensionless number that gives the indication of the light bending ability of that medium. The refractive index … See more The relative refractive index of an optical medium 2 with respect to another reference medium 1 (n21) is given by the ratio of speed of light in medium 1 to that in medium 2. This can be expressed as follows: See more Refractive index also varies with wavelength of the light as given by Cauchy's equation: The most general form of Cauchy's equation is Usually, it is sufficient to use a two-term form of the equation: See more When light passes through a medium, some part of it will always be absorbed. This can be conveniently taken into account by defining a complex refractive index, See more Thomas Young was presumably the person who first used, and invented, the name "index of refraction", in 1807.
