Why is pencil immersed in water seems bend

Answer 1

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.

Answer 2

Answer:

Rays coming from the pencil on travelling from denser medium to a rarer medium bend away from the normal. However when our eyes receive the rays, our brain draws a straight line and to us the rays appear to emerge from a higher point. Hence the pencil appears to be bent when immerge in water.
