WebThis article deals with the refractive index formula and its derivation. Refractive index refers to a value which has common usage in optical science. Furthermore, it has no unit. Refractive Index indicates a material’s ability to refract light.In order to properly understand the concept of refractive index, one must become familiar with the concept of refraction. WebThe refractive index of a material depends on the optical frequency or wavelength; this dependency is called chromatic dispersion.Typical refractive index values for glasses and crystals (e.g. laser crystals) in the visible spectral region are in the range from 1.4 to 2.8, and typically the refractive index increases for shorter wavelengths (normal dispersion).
