It is a dimensionless number that depends on the temperature of the medium and the wavelength of the light beam. In simple words, the index of refraction describes how fast a light beam travels through a medium compared to a vacuum. This relationship is described by the formula: n = c ...
Refractive index, measure of the bending of a ray of light when passing from one medium into another.
If the refractive index is known, one can determine either the real or apparent depth if the other is known. Summary:The refractive index (μ) of a medium relates to the real depth (h) and the apparent depth (h') of an object submerged in that medium by the formula:μ=hh′Updated ...
Optical materials can be properly designed by knowing its refractive index and the parameters related to it. Cauchy had introduced an empirical formula for the refraction index of a medium, and its relation to wavelength of the incident light, as [6]n=A+Bλ2+Cλ4+⋯,where A, B and C...
Related to Relative refractive index:Absolute refractive index,Snell's law (Opt.)the ratio of the sine of the angle of incidence to the sine of the angle of refraction for a ray passing out of one of the media into the other. See also:Refractive ...

A Sellmeier formula is an equation for calculating the wavelength-dependent refractive index of a medium.
The radio refractive index formula adopted in 1963 by the International Union of Geodesy and Geophysics (IUGG) and the International Association of Geodesy (IAG) is being reviewed. Forty years ago, this formula was essential for the reduction of distances measured with microwave EDM instruments. Sin...
Focuses on a study on which developed an analytic formula for the refractive index of Al[subx]Ga[sub1-x]As semiconductor below the band edge. Composition dependence of the fitting parameters; Analysis of errors; Significance of empirical fit.Deri...
The refractive index (or index of refraction) of a medium is a measure for how much the speed of light (or other waves such as sound waves) is reduced inside the medium. For example, typical soda-lime glass has a refractive index of 1.5, which means that in glass, light travels at ...
