One of the most important things to remember about waves is that they transport energy, not matter. This makes them different from other phenomenons in physics. Many waves cannot be seen such as microwaves and radio waves.

The most important of these is visible light, which enables us to see. Radio waves have the longest wavelengths of all the electromagnetic waves. They range from around a foot long to several miles long.

And then Waves in the ocean are mostly generated by the wind moving across the ocean surface. ... One of the most important things to remember about waves is that they transport energy, not matter.
