Two boats are anchored in the harbor, separated by a horizontal distance of 18 m. The
boats bob up and down as waves enter the harbor. When one boat is at its highest point,
the other is at its lowest point and there are no wave crests between them. Each boat
makes exactly 12 complete up-and-down cycles every 48.0 s. The vertical distance
between a boat's highest and lowest position is 1.2 m. Draw the diagram, showing where
the second boat is located. Then determine the wavelength (m), frequency (Hz), period (s),
amplitude (m), and speed (m/s) of the waves.
