Options

A. The same phase as the incident pulse but with velocity reversed
B. A phase change of `180^(@)` with no reversal of velocity
C. The same phase as the incident pulse with no reversal of velocity
D. A phase change of `180^(@)` with velocity reversed

Answer

Explanation

Reflection from fixed end, a phase difference of `pi` is introduced.
