Question

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 ?

Answer 1

Answer:

When a ray incident on the air-Turpentine interface, the ray bends towards the normal because the Turpentine is denser than the air medium. The optical density of Turpentine is higher than that of the water, so when a light ray incident on the Turpentine-water interface, ray bends away from the normal
