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

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

Answer

C

Explanation

When the pulse of the wave train reaches the fixed end , it is reflected back in the same medium, with a phase change of ` pi " or " 180^(@)` but the velocity is not changed.
