When a wave hits a wall or barrier, it bounces back with the same velocity/frequency/whatnot. Examples of this are an echo in a cave or shining that torch of yours at the mirror so it hits you in the eyes. All waves follow the law of reflection, which is: The angle of incidence is equal to the angle of reflection.
Can waves drag you out to sea?

It can drag you down, but it’s not truly treacherous because you won’t be held under for long. Just relax and hold your breath, and you’ll pop to the surface, often on the back side of the waves breaking near shore.

How far out do waves break?
Waves break when they reach a shallow coastline where the water is half as deep as the wave is tall. As a wave travels across the open ocean, it gains speed. When a wave reaches a shallow coastline, the wave begins to slow down due to the friction caused by the approaching shallow bottom.

What is it called when a wave is about to crash?
Plunging waves are formed when the incoming swell hits a steep ocean floor or a sea bottom with sudden depth changes. As a result, the wave’s crest curls over and explodes on the trough. The air under the lip of the wave is compressed, and a crashing sound is often heard.
Can you survive a rip current?
