Answer:
Refractive index is the measure of bending of a light ray when passing from one medium to another. It can also be defined as the ratio of the velocity of a light ray in an empty space to the velocity of light in a substance .
n = c/v
where , n is the refractive index of the medium
c is the velocity of light in vacuum
v is the velocity of light in the medium
