Question

what do you mean by refractive index ? what is Snell's law?​

Answer 1

Answer:

Snell's law is defined as “The ratio of the sine of the angle of incidence to the sine of the angle of refraction is a constant, for the light of a given colour and for the given pair of media”.

the ratio of the velocity of light in a vacuum to its velocity in a specified medium is known as refractive index

Answer 2

Answer:

Hey mate here is your answer.....

Refractive index:

Refractive index, also called index of refraction, measure of the bending of a ray of light when passing from one medium into another.

Snell's law :

Snell's law is defined as “The ratio of the sine of the angle of incidence to the sine of the angle of refraction is a constant, for the light of a given colour and for the given pair of media”.
