Answer:
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.

Explanation:
A pencil looks bent in water because of a phenomenon called refraction. When light enters water, it cannot move as fast as it does in air. As light enters water at an angle, it bends away from its original path, and this makes the image look bent.
