    A)  energy                                

    B)  momentum

    C)  velocity              

    D)         angular momentum

    Correct Answer: B

    Solution :

    If an electron and a photon propagates in the form of waves having the same wavelength, it implies that they have same momentum. This is according to de-Broglie equation                                 \[p\propto \frac{1}{\lambda }\]
