A wave pulse moves along a stretched rope in the direction shown. [diagram of a wave pulse on a rope with particle P marked] Which diagram shows the variation with time t of the displacement s of the particle P in the rope?

1. Agraph: s against t, negative rectangular pulse then positive triangular peak
2. Bgraph: s against t, positive triangular peak then negative rectangular pulse
3. Cgraph: s against t, negative triangular dip then positive rectangular pulse
4. Dgraph: s against t, positive rectangular pulse then negative triangular dip
