Refractive index of cubic zirconia stabilized with yttria, Appl. 14, K5-K8 (1966) Data The Refractive Index - n - of a medium is a measure for how much the velocity of light is reduced inside the medium. 1. Refractive index database Shelf. Many materials have a well-characterized refractive index, but these indexes often depend strongly upon the frequency of light, causing optical dispersion.Standard refractive index measurements are taken at the "yellow doublet" sodium D line, with a wavelength () of 589 nanometers.
