Standing wave

Standing waves

Standing wave in stationary medium. The red dots represent the wave nodes. A standing wave (black) depicted as the sum of two propagating waves traveling in opposite directions (red and blue).

Electric force vector (E) and magnetic force vector (H) of a standing wave. Standing waves in a string — the fundamental mode and the first 6 overtones.

A two-dimensional standing wave on a disk; this is the fundamental mode A higher harmonic standing wave on a disk with two nodal lines crossing at the center.

In physics, a standing wave – also called a stationary wave – is a wave that stays in a constant position.
