STANDARD Physics Refraction MCQ Question

Type: MCQ-conceptual-Medium-Class 12

The optical density of turpentine is higher than that of water while its mass density is lower. Figure shows a layer of turpentine floating over water in a container. For which one of the four rays incident on turpentine in figure, the path shown is correct?

A

(1)

B

(2)

C

(3)

D

(4)

Correct Answer

Option 2

Detailed Explanation

In the figure, the path shown for the ray 2 is correct. The ray suffers two refractions: At A, ray goes from air to turpentine, bending towards normal. At B, ray goes from turpentine to water (i.e., from denser to rarer medium), bending away from normal.
