A vibration generator produces a progressive wave on a rope. The diagram shows the rope at one instant. The wave travels at a speed of 4.0 m s–1. What are the wavelength and the frequency of the wave?

1. Awavelength 0.13 m, frequency 15 Hz
2. Bwavelength 0.13 m, frequency 30 Hz
3. Cwavelength 0.27 m, frequency 15 Hz
4. Dwavelength 0.27 m, frequency 30 Hz
