    Which of the following figures represent the variation of particle momentum and the associated de-Broglie wavelength? [NEET  2015]

    A)     

    B)       

    C)                    

    D)        

    Correct Answer: B

    Solution :

         
    The de-Broglie wavelength is given by
    \[\lambda =\frac{h}{P}\]
    \[\Rightarrow \]   \[P\lambda =h\]
    This equation is in the form of \[yx=c,\] which is the equation of a rectangular hyperbola. Hence, the graph given in option [b] is the correct one.
