Question

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.

Answer 1

Hint— No. Bending will be different in different liquids since
velocity of light at the interface separating two media depends on
the relative refractive index of the medium.
