Given:
Speed of sound c = 340 m/s.
Waelength λ = 1.70 m.
Frequency f = c / λ = 340 m/s / 1.70 m = 200 Hz (1/s).

If the sound of the ships whistle travels 340 meters in one second and the waves are l.70 meters apart
just divide the distance traveled 340 meters by the distance between waves to get
200 waves per second for the frequency
Frequency = speed of waves per second over wavelength
