There are no units for the index of refraction, because it is merely a ratio. When you use the formula n = c/v, the units for c and v cancel each other out, because they are both measured in m/s, leaving no units.

A ray of light being refracted in a plastic block In optics, the refractive index (also known as refraction index or index of refraction) of a material is a dimensionless number that describes how fast light travels through the material. It is defined as where c is the speed of light in vacuum and v is the phase velocity of light in the medium. Interspecimen comparison of the refractive index of fused silica, J. Opt. Soc.

The index of refraction forms the basis of Snell's law, which quantitatively determines the deviation of light rays traversing a surface separating two media of different refractive indices.

Refractive Index. is defined as the velocity of light in vacuum relative to the velocity in the polymer. Snellius' Law. describes the relationship between angle of incidence and the angle of transmission or refraction. The sine of the angle of incidence to the sine of the angle of refraction is equal to the refractive index, n.

The refractive index variable is most commonly symbolized by the letter n or n' in descriptive text and mathematical equations. The refraction index has no unit as it is the ratio of two similar Quantities. The index of refraction, or refractive index, is a measure of how fast light rays travel through a given medium.

First off all, one must apply the Snell’s law as follows: For a ray which goes from the air to a medium Refraction is an effect that occurs between transparent materials of different densities. The Refractive Index - n - of a medium is a measure for how much the velocity of light is reduced inside the medium. Consequently, the index of refraction varies accordingly, being greater for short wavelengths (blue) than for longer wavelengths (red). The index of refraction forms the basis of Snell's law, which quantitatively determines the deviation of light rays traversing a surface separating two media of different refractive indices. The refractive index or index of refraction (n. D) is one of the physicochemical properties of substances (optical medium).
