Answer 1

Explanation:

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:

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

An example of refraction is a bending of sunrays as they enters rain drops,forming a rainbow.
