Answer
The angle of the wave refracts and gets closer to the normal.
Work Step by Step
As waves come closer to the shore, the water depth decreases, causing the waves to slow down.
As the wave slows down, the angle of the wave refracts and gets closer to the normal, just like rays of light when they enter a material with a higher index of refraction.
The angle of the wave refracts and gets closer to the normal.
