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

Answer:

yes ,but if may not appear to bent the same as in water because liquids like kerosene and turpentine have different refractive index

Answer 2

$\large\mathcal\blue{Aɳʂɯҽɾ:→}$

Bending of light here is a function of refraction. Refraction is dependent on refractive indices. Refractive indices of kerosene or turpentine would not be the same as water. Hence degree of bend would be different in different mediums.
