The diagram shows a displacement-distance graph of a progressive transverse wave propagating along a rope.
The wave has a frequency of 5.0 Hz. What is the speed of the wave?
0.15 m s−10.15\text{ m s}^{-1}0.15 m s−1
0.30 m s−10.30\text{ m s}^{-1}0.30 m s−1
0.60 m s−10.60\text{ m s}^{-1}0.60 m s−1
3.0 m s−13.0\text{ m s}^{-1}3.0 m s−1
