Question

State the laws of refraction and explain absolute refractive index

Answer 1

Answer:

Laws of refraction :

(1)the angle of incidence, angle of refraction and the normal always lie on same plane.

(2) the ratio of the sin of angle of incidence to sin of angle of refraction is always equal to the constant that is the refractive index .

Explanation:

Absolute refractive index:

the refractive index of a medium with respect to air is called absolute refractive index .
