WebRefractive Index (Index of Refraction) is a value calculated from the ratio of the speed of light in a vacuum to that in a second medium of greater density. The refractive index variable is most commonly symbolized by the letter n or n' in descriptive text and mathematical equations. Webangles is exceeded, total reflection occurs. The refractive index is calculated from this critical angle. As the refraction depends on the wavelength of the incident light, the refractive index is measured at the wavelength of the D line of sodium (589.3 nm) as standard and symbolized by nD. The refractive index depends not only on the wavelength
