To practice problem-solving strategy 15.2 standing waves. in lab, your instructor generates a standing wave using a thin string of length l = 1.95 m fixed at both ends. you are told that the standing wave is produced by the superposition of traveling and reflected waves, where the incident traveling waves propagate in the +x direction with an amplitude a = 3.75 mm and a speed vx = 13.5 m/s . the first antinode of the standing wave is a distance of x = 32.5 cm from the left end of the string, while a light bead is placed a distance of 16.3 cm to the right of the first antinode. what is the maximum transverse speed vy of the bead? make sure to use consistent distance units in your calculations.
