Question

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 phase change of 180° with speed changed, The same phase as the incident pulse with no reversal of velocity, A phase change of 180° with no change of speed, The same phase as the incident pulse but with velocity reversed

MARKS App · Accepted Answer

When a pulse of a wave train travels along the stretched string and reaches the fixed end of the string, then it will be reflected back to the same medium. the reflected ray suffers a phase change of π with the incident wave but wave speed after reflection does not change.
