A fisher has anchored her 11 m long boat far away from the shore. The waves in the water cause the boat to rock, and the boat performs 12 vertical oscillations within 7 s. The wave crests travel from bow (front) to stern (back) of the boat in 4 s. She notes that at time t = 0 the bow of the boat is at the top of a wave. She then observes the wave phase at bow again at t = 1 s What is the period of waves? T=1 What is the wavelength? A S m What is the number of complete waves that fits in the length of the boat simultaneously? nwaves =
