Quizplus · Accepted Answer

When the incident pulse reaches the splice, it will create a reflected pulse that travels up the rope. The reflected pulse will experience a phase shift of 180 degrees at the splice due to the change in direction of the rope, and will be inverted. This means that the top and bottom sections of the rope will switch places, so the correct answer is C.
