The Figure shows two waves, A and B, travelling along a long rope at the same instant.
Figure

Compare the amplitude and the wavelength of wave A with those of wave B.
The frequency of wave A is 0.50 Hz.
Calculate the speed of wave A.
Both waves travel at the same speed.
Calculate the frequency of wave B.
Calculate the time taken for wave B to travel 30 m along the rope.
