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.
A shoreline is not static. As waves appoach shore and âfeel the bottomâ, water piles up and breakers form (see âWavesâ). Primarily these waves, breaking at an angle to the shoreline, are what generate a âlongshore currentâ that parallels the shore. Importantly, the longshore current not only moves water in the surf zon.
