WebMany materials have a well-characterized refractive index, but these indexes often depend strongly upon the frequencyof light, causing optical dispersion. Standard refractive index measurements are taken at the "yellow doublet" sodium D line, with a … 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 determines how much the path of light is bent, or refracted, when entering a material. This is described by Snell's law of refraction, n1 sin θ…
