Refractive index - Wikipedia, the free encyclopedia 
 
en.wikipedia.org/wiki/Refractive_index
In optics the refractive index or index of refraction n of an optical medium is a dimensionless number that describes how light, or any other radiation, propagates through that medium.

Many materials have a well-characterized refractive index, but these indices depend strongly upon the frequency of light. Standard refractive index measurements are taken at the "yellow doublet" sodium D line, with a wavelength of 589 nanometers. There are also weaker dependencies on temperature ...
