A transverse wave is travelling along a rope. The frequency of the wave is 2.0 Hz. The graph shows the variation with distance of the displacement of the wave at time t = 0. [Figure showing a sinusoidal wave (displacement vs distance) at t=0, with peaks at 2m and 10m, and a trough at 6m. Direction of wave travel is right.] Which diagram shows the position of the wave at time t = 0.5s?
Awave pattern with its first peak at 0 m and first trough at 2 m.
Bwave pattern with its first trough at 2 m and first peak at 4 m.
Cwave pattern with its first peak at 2 m and first trough at 6 m (identical to the t=0 graph).
Dwave pattern with its first peak at 3 m and first trough at 7 m.
