Chapter 14, Problem 55A

To determine

To Explain:

The position of a point on rope before the pulse has arrived compared to the position of its point after the pulse has passed.

Answer to Problem 55A

After pulse has passed, the position of point is exactly the same as it was before the pulse reached the point.

Explanation of Solution

Introduction:

Pulse is defined as the single disruption that go through a transmission medium. The medium through which the pulse passes can be a vacuum or matter.

When you consider a pulse that moves through a rope and it reaches to the end it will reflect on the basis of the pattern that will depend on whether the rope is fixed or free to move at the free end. There is a free and fixed end of the pulse.The amplitude of a pulse is measured by how far the medium has travelled from the initial position of rest.

A pulse is defined as only a disturbance that can move through a medium.The waves of a rope are in transverse form. In transverse pulse like rope all the particles are disturbed by the pulse which is perpendicular to the direction at which the pulse moves.

Conclusion:

Hence, the position of a point along the rope is the same as it was before when the pulse arrived to the position when the pulse has passed.
