A harmonic wave is traveling along a rope. It is observed that the oscillator that generates the wave completes 40.0 vibrations in 30.0 s. Also, a given maximum travels 425 cm along the rope in 10.0 s. What is the wavelength?

The wave speed is
V = (425 cm)/(10 s) = 4.25 cm/s

The frequency is
f = 40/30 = 1.333 cycles per second

The wavelength is the wave speed divided by the frequency.
