In physics, a standing wave – also known as a stationary wave – is a wave that remains in a constant position. This phenomenon can occur because the medium is moving in the opposite direction to the wave, or it can arise in a stationary medium as a result of interference between two waves traveling in opposite directions. In the second case, f...

The interference pattern produced by two waves of equal amplitude and frequency travelling in opposite directions. The pattern is characterized by alternating nodal and antinodal regions. Only the standing wave, the interaction of these two waves meeting, is stationary.AcousticsIn room acoustics, an apparently stationary waveform created by multipl...

In physics, a wave in which the positions of nodes (positions of zero vibration) and antinodes (positions of maximum vibration) do not move. Standing waves result when two similar waves travel in opposite directions through the same space. For example, when a sound wave is reflected back along its own path, as when a stretched string is plucked, st...
