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 a … 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 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, $${\displaystyle {\underline {n}}=n+i\kappa .}$$ 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 … 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 … See more 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 … See more WebRefractive Index. Refractive Index is the ratio of the speed of light in a vacuum to the speed of light in the specified material - a description of …
