3 . If the wave shown in problem 1 is actually a standing wave on a string (with the same frequency of 120 Hz), answer the following questions: a) Which harmonic is shown?I b) What is the fundamental frequency? C) What is the wavelength of the fundamental frequency? 1. The figure shows a "snapshot" of a wave at a given instant of y (m) time. The frequency of this wave is 120 Hz. What are the (a) 0.10 amplitude, (b) wavelength, and (c) speed of this wave? 0 -0.10 0 0.10 0.20 0.30
