A pencil when dipped in water in a glass...

A pencil when dipped in water in a glass tumbler appears to be bent at the interface of air and water. Will the pencil appear to be bent to the same extent, if instead of water we use liquids like, kerosene or turpentine. Support your answer with reason.

Text Solution

Verified by Experts

The bending of pencil will increase, The optically denser medium will cause more refraction (or more bending) of light rays.
