Nick and Kara were lounging on rafts in the shallow waters of the beach at Lake Bluebird. They were spaced 1.8 meters apart. A motor boat zoomed past creating ripples which traveled towards Nick and Kara. Nick and Kara's rafts began to bob up and down as the ripples passed by them, making exactly 4 up and down cycles in 8.4 seconds. When Nick's raft was at a high point, Kara's raft was at a low point and there were no crests between their boats. Determine the wavelength, frequency and speed of the ripples Assume that the ripples traveled in a direction parallel to the imaginary line connecting the two rafts.
