A pulse of a wave train travels along a stretched string and reaches t

1.	A pulse of a wave train travels along a stretched string and reaches the fixed end of the string.it will be reflected back withA. a phase change of `180^(@)` with velocity reversedB. the same phase as the incident pulse with no reversal of velocityC. a phase change of `180^(@)` with no reversal of velocityD. the same phase as the incident pulse but with velocity reversed
Answer» Correct Answer - C 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 n with the incident wave but wave velocity after reflection does not change.
