Figure 1 shows an observer standing on a pier, watching waves on the sea surface travel past an anchored marker buoy.

An observer on a wooden pier is looking out at the sea. A few meters away from the pier, there is a stationary, anchored red marker buoy. Waves are shown as parallel crests propagating past the buoy. The observer is holding a smartphone with a digital stopwatch display timer.

The observer has a stopwatch.

Describe how the observer could determine the frequency of the waves passing the buoy.
