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
Answer
2
Explanation
Solution
: 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.
