    Photon and electron are given energy \[({{10}^{-2}}\,J).\]  Wavelengths  associated  with photon and electron are\[{{\lambda }_{ph}}\]and\[{{\lambda }_{el}}\]then, correct statement will be

    A) \[{{\lambda }_{ph}}>{{\lambda }_{el}}\]

    B)  \[{{\lambda }_{ph}}<{{\lambda }_{el}}\]

    C)  \[{{\lambda }_{ph}}={{\lambda }_{el}}\]

    D)  \[\frac{{{\lambda }_{el}}}{{{\lambda }_{ph}}}=c\]

    Correct Answer: A

    Solution :

     Wavelength of photon will be greater than that of electron because mass of photon is less than that of electron \[\Rightarrow \] \[{{\lambda }_{ph}}>{{\lambda }_{el}}\]
