    Which of the following expressions gives the de-Broglie relationship?

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

    B)  \[\lambda =\frac{h}{mv}\]

    C)  \[\lambda =\frac{h}{mp}\]                        

    D)  \[\lambda \,m=\frac{v}{p}\]

    Correct Answer: B

    Solution :

                     The de-Broglie relation is, \[\lambda =\frac{h}{mv}\] Where, \[\lambda =\] de-Broglie wavelength \[h\text{ }=\]Plancks constant \[m\text{ }=\]mass of particle  and   \[~v=\] velocity of particle
