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. [graph: displacement against distance / m, showing a sinusoidal wave with direction of wave travel to the right] Which diagram shows the position of the wave at time t = 0.5 s?
- A[graph A: displacement against distance / m]
- B[graph B: displacement against distance / m]
- C[graph C: displacement against distance / m]
- D[graph D: displacement against distance / m]
