The disturbance travels out from the center of the pattern, but the water does not travel with the wave. If the relative amplitude of oscillation at different points in the field remains constant, the wave is said to be a standing wave.

The sound energy is transferred from one molecule to another and so travels along the wave. This is done by a series of disturbances or vibrations that carry the energy. It is independent of the source producing the wave. A wave is a disturbance that travels or propagates and transports energy and momentum without the transport of matter. When two waves travel in a medium simultaneously in such a way that each wave represents its separate motion, then the resultant displacement at any point at any time is equal to the vector sum of the individual displacements of the waves. Wave motion is classified into three different ways they are, the medium of propagation, the dimensions in which a wave propagates energy, the energy transfer.
