The refraction through the prisms are as shown. Pick out the wrong statement from the following. Path of the light ray in
Options
- Aa is correct if n₂>n₁ and n₂>n₃
- Bb is correct if n₁=n₂ and n₂>n₃
- Cc is correct if n₂ < n₁ and n₂=n₃
- Dd is correct if n₁>n₂ and n₂ < n₃
Correct answer
A. a is correct if n₂>n₁ and n₂>n₃
Step-by-step solution
Since at the second surface light ray grazes along the surface of prism so, n₂>n₁ At first surface, light suffers refraction, So, n₂>n₃
