A pulse of a wave train travels along a stretched string and reaches the fixed end of the string. It will be reflected back with
- A a phase change of \(180^{\circ}\) with velocity reversed
- B the same phase as the incident pulse with no reversal of velocity
- C a phase change of \(180^{\circ}\) with no reversal of velocity
- D the same phase as the incident pulse but with velocity reversed
Answer & Solution
Correct Answer
(C) a phase change of \(180^{\circ}\) with no reversal of velocity
Step-by-step Solution
Detailed explanation
A pulse of a wave train when travels along a stretched string and reaches the fixed end of the string, then it will be reflected back to the same medium and the reflected ray suffers a phase change of \(\pi\) with the incident wave but wave velocity after reflection does not change.
