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
Options
- Aa phase change of 180^ with velocity reversed
- Bthe same phase as the incident pulse with no reversal of velocity
- Ca phase change of 180^ with no reversal of velocity
- Dthe same phase as the incident pulse but with velocity reversed
Correct answer
C. a phase change of 180^ with no reversal of velocity
Step-by-step solution
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 with the incident wave but wave velocity after reflection does not change.
