Interference of Rectangular Pulses. Figure I5.3S shows two rectangular wave pulses on a stretched string traveling toward each other. Each pulse is traveling with a speed of 1.00 mm/s and has the height and width shown in the figure. If the leading edges of the pulses are 8.00 mm apart at t = 0, sketch the shape of the string at t = 4.00 s, t = 6.00 s, and t = 0.0 s.

4.00 mm v = 1.00 mm/s 3.00 mm - 8.00 mm 4.00 mm v = 1.00 mm/s 4.00 mm
