Refraction

The video explains how waves change velocity when moving from one medium to another. It describes how waves bend when entering a slower medium at an angle, with one end of the wavefront slowing down first. This bending effect is most noticeable with light but occurs with all types of waves.

What happens to a wave when it passes into a slower medium at an angle?

How does the bending of a wave occur when it enters a new medium?

Can you explain why the wavefront bends when one end is slowed down?

In what way do we notice the effect of wave behavior most easily?

Does the phenomenon of wave bending occur with all types of waves?
