Question

Q.4. A light ray enters from medium A to medium B
as shown in the figure. The refractive index of
medium B relative to A will be
Medium B
MediumA
(a) Greater than unity (b) Less than unity
(c) Equal to unity
(d) Zero
INCERT Exemp.)
Ans. Correct option: (a)
Explanation : Since, light rays in medium B go
towards normal, so it has greater refractive 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.
O
onto is true?​

Answer 1

Answer:

Correct option: (a)

Explanation:

Since, light rays in medium B go

towards normal, so it has greater refractive 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.
