Answer 1

Answer:

refractive index, also called index of refraction, measure of the bending of a ray of light when passing from one medium into another. ... Refractive index is also equal to the velocity of light c of a given wavelength in empty space divided by its velocity v in a substance, or n = c/v.

Answer 2

$ANSWER$

The 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.

The refractive index of a medium can be calculated using the following formula:

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
