Consider an extended object immersed in water contained in a plane through. When seen from close to the edge of the through, the object looks distorted because.

A

the apparent depth of the points close to the edge are nearer the surface of the water compared to the points away from the edge

B

the angle subtended by the image of the object at the eye is smaller than the actual angle subtended by the object in air

C

some of the points of the object far away from the edge may not be visible becuse of total internal reflection

D

water in a trough acts as a lens and magnifies the object

Text Solution

Verified by Experts

The correct Answer is:
1,2,3

When light from the submerged object before reaching to the obeiver gets refracted from water surface, the rays bend away from normal and the angle subtended by the image of the object at the eye is smaller than the actual angle subtended by the object in air. Also the apparent depth of the points close to the edge are nearer the surface of the water compared to the points away Horn the edge.
As we move towards right, the angle of incident increases and becomes equal to critical angle. Hence some of the points of the object far away from the edge ma y not be visible because of total internal reflection.
