Question

How is refractive index of a medium related to velocity of light in the medium?​

Answer 1

Answer:

As the wave travels into the less dense medium, it speeds up, bending away from the normal line. The index of refraction tells the ratio of the velocity in a vacuum in relation to the velocity the medium; thus, the velocity will be greater in a medium with a lower index of refraction.

Answer 2

Explanation:

if the velocity of light increases in the medium then the refractive index of that will be decreases

n is directly proportional to 1/v
