Question

What is refractive index ? What does it represents

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.

Explanation:

Where, n is the refractive index. c is the velocity of light in a vacuum ( 3 × 108 m/s) v is the velocity of light in a substance.
