$A$ 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.

(B) No,the pencil will not appear to be bent to the same extent. The extent of bending of the pencil depends on the refractive index of the liquid used. Since different liquids like kerosene and turpentine have different refractive indices compared to water,the angle of refraction will vary. The bending of light at the interface of two media is determined by the relative refractive index,which dictates the change in the velocity of light as it passes from one medium to another.
