Consider two identical and symmetrical wave pulses on a string. Suppose the first pulse reaches the fixed end of the string and is reflected back and then meets the second pulse. When the two pulses overlap exactly, the superposition principle predicts that the amplitude of the resultant pulses, at that moment, will be what factor times the amplitude of one of the original pulses?

At t = 0, the instantaneous position of two pulses moving along a taut string with a speed v = 19.0 cm/s are as shown in the diagram below. Each unit on the horizontal axis is 5.0 cm and each unit on the vertical axis is 2.0 cm. (The peak of pulse 2 is exactly on a half unit of the horizontal axis.) (a) At what location will the resultant of the two pulses have maximum amplitude? (b) At what...

Two wave pulses are heading toward each other on a string. One pulse is "up" and the other is the exact same shape, inverted (i.e. "down"). At the moment the pulses cross the string is perfectly horizontal. What happened to the energy in the wave?

Two wave pulses of equal width and amplitude, but of different shapes, travel along a string toward one another as shown. 1) 0.5 m 0.5 m 0.5 m 1.0 m 2) 0.5 m 1.0 m For each of the two situations, select the waveform from the options below that represents the superposition of both pulbes at the insta when they overlap completely. E.g, if the answer to the first is A and to the second, G, enter AG. You only...
