Question

What does wave refraction cause?

Answer 1

a part of incident and reflected ray is absorb by the surface and the remaining part travells along usually in a straight path

Answer 2

Wave Refraction and Coastal Defences. Friction with the sea bed as waves approach the shore causes the wave front to become distorted or refracted as velocity is reduced. ... Since the paths of the waves in the bay are diverging or spreading out, wave energy is much reduced, allowing deposition to occur.
