A child who has become bored with fishing, passes time by shaking her 1.62 m long, fibreglass fishing rod. This action creates a transverse standing wave with the handle being a node on one end and the far end being an anti-node. At one instant she shakes the rod with a frequency of 5.56 Hz to get a standing wave. When she increases the frequency of the shake to 7.15 Hz she sees the next standing wave pattern. All answers have a tolerance of ±5 on the third signficant digit. a) Calculate the frequency she must shake the rod to create a fundamental standing wave pattern. Hz 3.70 b) Calculate the wavelength of the 5.56 Hz wave. Number Units
