  • Explain how water waves are reflected from concave and convex surfaces.

Everything You'll Have Covered

What factors determine the reflection shape of a wave that impinges onto a surface?

~ The reflection shape of a wave that impinges onto a surface is determined by the direction of the incoming wave and the shape of the obstacle onto which the wave impinges.

What happens when a wave impinges onto a linear object that is parallel to the wave itself?

~ When a wave impinges onto a parallel linear object, the wave is reflected back parallel to the object.

What happens to the reflection of a wave when it impinges onto a non-parallel object?

~ When a wave impinges onto a non-parallel object, it is reflected off the object at an angle that is equal to the angle at which the wave strikes the surface.

What happens when a wave impinges onto a curved surface?

~ When a wave impinges into a curved surface, it is reflected back in the shape of the surface.
