What are 5 things that have waves but are not in the ocean?

Waves can be found in various contexts outside the ocean. For example, sound waves propagate through air, allowing us to hear. Light waves travel through space, enabling us to see. Additionally, seismic waves occur during earthquakes, and radio waves are used for communication in devices like radiOS and cell phones. Lastly, waves can also manifest in the form of ripples on a pond's surface when a stone is thrown in.
