Question

(i) On entering in a medium from air, the speed of light becomes half of its value in

air. Find the refractive index of that medium with respect to air?​

Answer 1

Answer:

the ratio of their refractive indices(R.I.) is 2:1

Explanation:

R.I.=c/v c=velocity of light in air or vaccum=constant.

So, R.I. inversely proportional to velocity.

hence if velocity become half then Refractive index(R.I.) will become 2 times of initial
