    A wave travelling in air falls on a glass plate. It is partly reflected and partly refracted. The phase difference between the reflected and refracted waves is

    A)  zero                                     

    B)  \[\pi \]/2

    C) \[\pi \]                                 

    D)  2\[\pi \]

    Correct Answer: C

    Solution :

                     The incident wave and reflected wave are always in phase whereas incident wave and refracted wave has phase difference of \[\pi \]. Therefore, phase difference between reflected wave and refracted phase is again n.
