Transcription: Ocean waves are a good example of transverse waves. The medium in which the waves travel is the water of the ocean. The wave oscillates this medium vertically. In other words, the water rises and falls as a result of the wave. However, the wave's propagation is horizontal. In other words, the wave approaches the shore. So its propagation is perpendicular to its oscillation. That makes it a transverse wave. Exverse Wave.
