The picture shows the profile of the string at t =and at t =seconds. The amount of displacement of the medium at any given location is simply the vector sum of the displacement of the two individual waves at that location AP PHYSICS Maloney Chapter/Waves and Interference WS Consider two pulses propagating in opposite directions along a string. This is the same situation as above, except that the pulse traveling to the The correct answer isThis is wave interference via superposition. WorksheetWav
