I. EXPERIMENT 1.10: STANDING WAVES ON STRINGS A. Abstract Waves on a string under tension and fixed at both ends result in well-defined modes of vibration with a spectrum of frequencies given by the formula below B. Formulas ē In=n (), n = 1,2,3,... v=JI where fn is the frequency of the nth standing wave mode on the string of length L, linear mass density , and under tension T, and v is the wave speed on the string. c. Description -0.9 m - FIG. 1. Standing wave set-up. The figure above shows the experimental set-up. An electro-mechanical device vibrates the end of a string of length, L, under tension. The tension is created by a weight, T = Mg, hanging over a pulley. The frequency of vibration is adjusted until an identifiable mode of standing wave is realized. In the figure, the mode has n = 4 anti-nodes (locations of large amplitude). In the experiment, this parameter will be fixed.
