21N.2.SL.TZ0.b.ii

A longitudinal wave travels in a medium with speed 340 m s−1. The graph shows the variation with time t of the displacement x of a particle P in the medium. Positive displacements on the graph correspond to displacements to the right for particle P.

Another wave travels in the medium. The graph shows the variation with time t of the displacement of each wave at the position of P.

Identify a time at which the displacement of P is zero.
