The graph shows how the vertical displacement of a sinusoidal travelling wave varies with distance along the path of the wave. A graph of vertical displacement in cm on the y-axis versus horizontal distance in cm on the x-axis. The y-axis ranges from -6 to 6 with major grid lines every 2 cm. The x-axis ranges from 0 to 45 with major grid lines every 5 cm. The wave starts at its maximum displacement of 4 cm at x = 0. It reaches its first minimum at x = 15 cm and returns to its maximum at x = 30 cm, completing one full cycle. The wave then continues to reach a minimum at x = 45 cm. The speed of the wave is 1.2 m s−11.2 \text{ m s}^{-1}1.2 m s−1.

What is the frequency of the wave?
