A stationary wave is set up on a stretched string. The diagram shows the string at two instants of time when it has maximum displacement. [diagram of stationary wave with point P] The oscillations of point P on the string have amplitude A. What is the distance moved by P from the position shown in the diagram after half a time period of the wave?
