A standing wave is one that moves back and forth between two boundaries while appearing to be stationary in time.
The stationary pattern of particle displacements from their equilibrium positions is the result of the superposition of direct and reflected waves, which results in the apparent motionlessness of the system.

What does "standing wave" mean?
A standing wave, also known as a stationary wave, is a combination of two waves that are both the same amplitude and frequency and are moving in opposite directions. Interference is the cause of the phenomenon; that is, when waves are superimposed, their energies are either added together or offset.
