Answer 1

When light travels through air and enters water at an angle, it changes direction due to refraction.

Step-by-step explanation:

When light traveling through air enters water at an angle, it moves along straight lines in air and changes direction when it enters water.

This phenomenon is known as refraction, which occurs because light travels at different speeds in different mediums.

An example of this is when a pencil appears bent when partially immersed in water due to the refraction of light.
