Explanation:
The pencil appears to be bent when it is kept in a glass tumbler with water due to refraction of light. The refraction of light occurs when the speed of light changes when it travels from one medium to another. But when the pencil is dipped in kerosene or in oil, the bending is not the same because they are optically denser than water.
