Answer:

Refractive 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.

Formula

Formulan=\frac{c}{v}

Formulan=\frac{c}{v}n = refractive index

Formulan=\frac{c}{v}n = refractive index{c} = speed of light

Formulan=\frac{c}{v}n = refractive index{c} = speed of light{v} = phase velocity of light
