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: $${\displaystyle n_{21}={\frac {v_{1}}{v_{2}}}.}$$ If the reference medium 1 is vacuum, then the refractive index of … 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 At the atomic scale, an electromagnetic wave's phase velocity is slowed in a material because the electric field creates a disturbance in the charges of each atom (primarily the 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 … See more Optical path length Optical path length (OPL) is the product of the geometric length d of the path light follows through a system, and the index of refraction of the medium through which it propagates, See more Thomas Young was presumably the person who first used, and invented, the name "index of refraction", in 1807. At the same time he changed this value of refractive power into a single number, instead of the traditional ratio of two numbers. The ratio … See more Refractive index also varies with wavelength of the light as given by Cauchy's equation: The most general … See more The refractive index of materials varies with the wavelength (and frequency) of light.
