Consider two identical wave pulses on a rope having a fixed end. Suppose the first pulse reaches the end of the rope, is reflect

ed back, and then meets the second pulse. When the two pulses overlap exactly, what will be the amplitude of the resultant pulse?

Answer:

zero

Explanation:

Consider two identical wave pulses on a rope having a fixed end. Suppose the first pulse reaches the end of the rope, is reflected back, and then meets the second pulse, both waves will be out of phase by π radians. Therefore, they form destructive interference and hence the amplitude of the resultant pulse would be zero.
