In physics, a standing wave, also known as a stationary wave, is a wave that oscillates in time but whose peak amplitude profile does not move in space. The peak amplitude of the wave oscillations at any point in space is constant with respect to time, and the oscillations at different points throughout the wave are in phase .
In the experiment, mechanical waves traveled in opposite directions form immobile points, called nodes. These waves were called standing waves by Melde since the position of the nodes and loops (points where the cord vibrated) stayed static. Standing waves were first discovered by Franz Melde, who coined the term "standing wave" around 1860.
A standing wave is a continuous form of normal mode. In a standing wave, all the space elements (i.e. (x, y, z) coordinates) are oscillating in the same frequency and in phase (reaching the equilibrium point together), but each has a different amplitude. The general form of a standing wave is:
The red dots represent the wave nodes. A standing wave, also known as a stationary wave, is a wave whose envelope remains in a constant position. This phenomenon arises as a result of interference between two waves traveling in opposite directions. The sum of two counter-propagating waves (of equal amplitude and frequency) creates a standing ...
In this animation, both waves have the same wavelength and the sum of amplitudes results in a standing wave. two waves permeate without influencing each other. Waves are usually described by variations in some parameters through space and time—for example, height in a water wave, pressure in a sound wave, or the electromagnetic field in a ...
The standing-wave oscillation frequency, multiplied by the Planck constant, is the energy of the state. A stationary state is called stationary because the system remains in the same state as time elapses, in every observable way.

Standing waves, in which each immobile point represents a node. Franz Emil Melde (March 11, 1832 in Großenlüder near Fulda – March 17, 1901 in Marburg ) was a German physicist and professor . A graduate of the University of Marburg under Christian Ludwig Gerling , he later taught there, focusing primarily on acoustics , [ 1 ] also making ...
