Refractive coefficient
http://hyperphysics.phy-astr.gsu.edu/hbase/phyopt/reflco.html The refractive index is an important property of the components of any optical instrument. It determines the focusing power of lenses, the dispersive power of prisms, the reflectivity of lens coatings, and the light-guiding nature of optical fiber. Since the refractive index is a fundamental physical property of … 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 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 … Zobraziť viac 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 … 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 … 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 the charges of each atom (primarily the electrons) proportional to the electric susceptibility of the medium. (Similarly, 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 defining a complex refractive index, Zobraziť viac

In physics and electrical engineering the reflection coefficient is a parameter that describes how much of a wave is reflected by an impedance discontinuity in the transmission medium. It is equal to the ratio of the amplitude of the reflected wave to the incident wave, with each expressed as phasors. For example, it is used in optics to calculate the amount of light that is reflected from a surface with a different index of refraction, such as a glass surface, or in an electrical transmissi…
