Sea waves are the propagation of the undulating shape of the sea surface, and are a wave formed by water particles leaving an equilibrium position, vibrating periodically and propagating in a certain direction. The vibration energy of water particles forms kinetic energy and the wave energy produces potential energy, and the cumulative amount of the two energies is surprising. In global oceans, the total energy of only the storms and swells is equivalent to half the solar energy reaching the outside of the earth. The energy of the ocean waves rolls forward in the direction of wave propagation. Thus, sea waves are in fact wave propagation of energy. The wave period of the sea waves ranges from a few tenths of a second to more than hours, the wave height ranges from a few millimeters to tens of meters, and the wavelength ranges from a few millimeters to thousands of kilometers.
