Question

a pulse is allowed to get reflected from the wall then​

Answer 1

Answer:A portion of the energy carried by the pulse is reflected and returns towards the left end of the rope. The disturbance that returns to the left after bouncing off the pole is known as the reflected pulse. A portion of the energy carried by the pulse is transmitted to the pole, causing the pole to vibrate

Explanation:

Answer 2

A pulse is reflected from the wall:

• When a pulse is reflected from the wall, then the phase changes due to reflection from the rigid boundary.

• When a pulse is reflected from the wall, then the phase changes due to reflection from the rare boundary.

• And the total phase angle also changes due to two reflections.
