Waves: Refraction

The video explains how waves behave when passing at an angle from one medium to another, focusing on the concept of refraction. It describes how waves bend due to changes in speed when moving between different media, such as air and water or through a diamond. The slowing down or speeding up of light causes this bending, known as refraction.

What is the significance of the bending of waves in the context of refraction?

Describe how the speed of light changes when it enters a different medium.
