A harmonic wave propagates along a string with speed c = 10 m/s, in the direction of increasing x. The figure is a snapshot of the string at t = 0. a) Find the wave function y(x, t) b) = T/2, T/4 and Plot y(x, t) for t T/8, where T is the period of the wave. y(x, 0) (m) c) What type of movement does each string element perform? Give the displacement of the element located at x = 15 m. Graph. 0.15 0.10 0.05 -0.05 -0.10 -0.16 AM x (m)
