Question

A ray of light while entering from medium A to medium B, bends slightly towards the normal.

Which of the following statements would be correct in this case ?

(i) Speed of light in medium A is less than the speed of light in medium B.

(ii) The optical density of medium A is more than the optical density of medium B.
(iii) the absolute refractive index of medium B is less than the absolute refractive index of medium A.

(iv) The absolute refractive index of medium B is more than the absolute refractive index of medium A.​

Answer 1

Explanation:

In going from medium A to B, the ray of light deviates towards normal, therefore, medium B must be denser compared to medium A. The refractive index of medium. A relative to B will be less than unity
