When ocean waves arrive at the relatively small opening of a jetty, the big lump of water at the opening oscillates according to the waves it keeps receiving from the ocean. Which one of the following explanations is wrong? The big lump of water just at the opening acts as an independent source for new waves that propagate into the jetty. The lump of water at the opening becomes the center for propagation of the new waves in all directions specially into the jetty. The new circular wave fronts that the lump of water at the opening generates appear to be bending the ocean waves into the jetty. This is called "refraction."
