Stationary Waves. Stationary or standing waves are formed in a medium when two waves having equal amplitude and frequency moving in opposite directions along the same line, interfere in a confined space. Generally, such waves are formed by the superposition of a forward wave and the reflected wave. Both longitudinal and transverse types of waves can form a stationary wave. When reflection occurs at a free end, there is no reversal of phase. i.e., a crest returns as a crest and a trough as a trough.
The surface of the Earthâs oceans is in constant motion, moving up and down in the form of waves. If you have been to a beach, you have witnessed waves first hand. Waves form as energy is transferred from molecule to molecule across the surface. In general, the water molecules move very little. It is only the energy that actually moves. However, as waves break across a shore or crash in violent storms, they can be the source for great mixing of an oceanâs water.
