Refractive index by wavelength
The refractive index of materials varies with the wavelength (and frequency) of light. This is called dispersion and causes prisms and rainbows to divide white light into its constituent spectral colors. As the refractive index varies with wavelength, so will the refraction angle as light goes from one material to another. … Zobraziť viac 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 … Zobraziť viac 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 … Zobraziť viac At the atomic scale, an electromagnetic wave's phase velocity is slowed in a material because the electric field creates a disturbance in … Zobraziť viac 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, Zobraziť viac 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 … Zobraziť viac 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 … Zobraziť viac When light passes through a medium, some part of it will always be absorbed. This can be conveniently taken into account by … Zobraziť viac http://www.philiplaven.com/p20.html
