Question

Madhum B
5. A light ray enters from medium A to medium
B as shown in Figure 10.2. The refractive
index of medium B relative to A will be
(a) greater than unity
(b) less than unity
(c) equal to unity
(d) zero
Medium​

Answer 1

Answer:

Since light rays in medium B goes towards normal. So it has greater restrictive index and lesser velocity of light with respect to medium A. So refractive index of medium B with respect to medium A is greater than unity.
