    If the momentum of the particle is tripled, then  de Broglie wavelength will:            

    A)              remain unchanged            

    B)              become 1/3

    C)                                     become 6 times  

    D)              become 2 times

    Correct Answer: B

    Solution :

    According to de Broglie theory the wavelength \[\lambda =\frac{\text{Plank }\!\!\!\!\text{ s}\,\text{constant}}{\text{momentum}}\] Hence if momentum is tripled then wave- length will become one third.
