    A pulse or a wave train travels along a stretched string and reaches the fixed end of the string. It will be reflected back with                                                                              [CBSE PMT 1997]

    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

    Correct Answer: D

    Solution :

               On reflection from fixed end (denser medium) a phase  difference of \[\pi \] is introduced.
