Refraction in ocean waves is identical to refraction in sound and energy waves in that it involves movement through a different medium. a. Trueb. False

True

Explanation:

Refraction is the change in the speed, wavelength and direction of a wave as it crosses the boundary between two different media of different densities.

Hence, refraction always involves the movement of a wave from one medium to another. This is the key point to be remembered whether we are discussing refraction in ocean waves or sound waves.
