  • question_answer Which of the following expressions gives the de-Broglie relationship       [MP PMT 1996, 2004; MP PET/PMT 1998]

    A)                 \[h=\frac{\lambda }{mv}\]          

    B)                 \[\lambda =\frac{h}{mv}\]

    C)                 \[\lambda =\frac{m}{hv}\]          

    D)                 \[\lambda =\frac{v}{mh}\]

    Correct Answer: B

    Solution :

               According to de-Broglie equation                                 \[\lambda =\frac{h}{mv},\,\,p=mv\], \[\lambda =\frac{h}{p}\], \[\lambda =\frac{h}{mc}\]
