Water Waves - Refraction.
Water
waves travel faster on the
surface of deep water
than they do on shallow water.
The change in speed of the wave
will cause refraction.

As you can see, the change in speed has
changed the direction of the wave.
The slower wave in the shallow water has a smaller wavelength.
The amount of refraction increases as the change in speed increases.
