    The de-Broglie wavelength of a particle is

    A)  proportional to its mass

    B)  proportional to its velocity

    C)  inversely proportional to its momentum

    D)  proportional to its total energy

    Correct Answer: C

    Solution :

     The de-Broglie wavelength of a particle is inversely proportional to its momentum. \[\lambda =\frac{h}{mv}\](de - Broglie equation) \[\therefore \] \[\lambda =\frac{h}{P}\](P = momentum)
