Q. A pulse of a wave train travels along a stretched string and reaches the fixed end of the string. It will be reflected with
A) A phase change of 180° with velocity reversed
B) The same phase as the incident pulse with no reversal of velocity
C) A phase change of 180° with no reversal of velocity
D) The same phase as the incident pulse but with velocity reversed
Explanation
(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 π with the incident wave but wave velocity after reflection does not change.
