10. Figure Q15.10 shows a history graph and a snapshot graph for a wave pulse on a string. They describe the same wave from two perspectives. a. In which direction is the wave traveling? Explain. b. What is the speed of this wave? Snapshot at t= 0.01 s - 6 Z-2 FIGURE Q15.10 y x (cm) 0.02 History at x = 2 cm 0.04 0.06 - t (s)
