Quizplus · Accepted Answer

The fact that the waves are approaching the shore at an angle to the shoreline indicates that they are being refracted, or bent, as they encounter a change in water depth or bottom structure. This is a common phenomenon that occurs when waves encounter headlands, bays, or other obstructions along a coastline. The refraction of waves causes them to undergo changes in speed, direction, and wavelength, which can affect their intensity and ability to erode or deposit sediments along the shore.
