  • question_answer
    Photon and electron are given same energy\[({{10}^{-20}}J)\]. Wavelength associated with photon and electron are\[{{\lambda }_{p}}\]and\[{{\lambda }_{e}}\]the correct statement will be

    A)  \[{{\lambda }_{p}}>{{\lambda }_{e}}\]

    B)  \[{{\lambda }_{p}}<{{\lambda }_{e}}\]

    C)  \[{{\lambda }_{p}}={{\lambda }_{e}}\]

    D)  \[\frac{{{\lambda }_{e}}}{{{\lambda }_{p}}}=c\]

    Correct Answer: A

    Solution :

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