Consider a very long string stretched along the x-axis, the string being at rest. Suppose that one end is held and given a sharp ‘flick’, setting it in motion. The disturbance set up by flicking the string will travel down the string. During the passage of the disturbance, each particle of the string remains at rest until the disturbance reaches it, at which instant the particle is displaced, returning to its original position once the disturbance has passed.
