The Refractive Index - n - of a medium is a measure for how much. In this study, the refractive index data.

^ "Table of Refractive Indices and Double Refraction of Selected Gems - IGS". Refraction is an effect that occurs between transparent materials of different densities. Refractive index is one of the important physical properties, which is widely used in separation and purification.

In general, an index of refraction is a complex number with both a real and imaginary part, where the latter indicates the strength of absorption loss at a particular wavelength-thus, the imaginary part is sometimes called the extinction coefficient k " (PDF). Thus, it is especially important to cite the source for an index measurement if precision is required. When n(1) is greater than n(2), the angle of refraction is always larger than the angle of incidence.Alternatively when n(2) is greater than n(1) the angle of.

There are several important points that can be drawn from this equation. There are also weaker dependencies on temperature, pressure/ stress, etc., as well on precise material compositions (presence of dopants, etc.) for many materials and typical conditions, however, these variations are at the percent level or less. Where n represents the refractive indices of material 1 and material 2 and are the angles of light traveling through these materials with respect to the normal. Standard refractive index measurements are taken at the "yellow doublet" sodium D line, with a wavelength of 589 nanometers.

Many materials have a well-characterized refractive index, but these indexes often depend strongly upon the frequency of light, causing optical dispersion.
