A string is attached to a vibrator as shown and a standing wave is set up by adjusting the frequency of oscillation. The mass per unit length of the string is 3.90×10-4 kg/m. The string is driven by an 84.0 Hz oscillator. The velocity of the wave traveling back and forth on the string is 49.2 m/s. The string has a length, L. A mass, M, (including the hanger) hangs from the end of the string after it passes over the pulley. Assume the two ends represent nodes of the standing wave. (a) What is the harmonic of the standing wave shown in the figure? A. 1 B. 2 C. 3 D. 4 E. 5 F. 6
