What concentrates wave energy or disperses it?
[ "wave diffusion", "wave reflection", "a prism", "wave refraction" ]
D
Wave refraction either concentrates wave energy or disperses it. In quiet water areas, such as bays, wave energy is dispersed. This allows sand to be deposited. Land that sticks out into the water is eroded by the strong wave energy. The wave energy concentrates its power on the wave-cut cliff .
