| 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: B
Solution :
| Option [b] is correct. |
| Explanation: \[{{\operatorname{µ}}_{A}}<{{\mu }_{T}}>{{\mu }_{W}}\] |
| As incidence ray passes from air to turpentine to water it means, from rare to denser then denser to rarer so first it bends towards normal then away from normal so the path shown is correct for ray (2) |
