    The energy of gamma \[(\gamma )\] ray photon is \[{{E}_{\gamma }}\]and that of an X-ray photon is \[{{E}_{x}}.\]If the visible light photon has an energy of \[{{E}_{\upsilon }},\] then we can say that

    A)  \[{{E}_{x}}{{E}_{\gamma }}{{E}_{v}}\]

    B)  \[{{E}_{\gamma }}>{{E}_{v}}>{{E}_{x}}\]

    C)  \[{{E}_{\gamma }}>{{E}_{x}}>{{E}_{v}}\]

    D)  \[{{E}_{x}}>{{E}_{v}}>{{E}_{\gamma }}\]

    Correct Answer: C

    Solution :

     \[{{E}_{\gamma }}\ge 100\,keV\] \[{{E}_{x}}=100eV\]to \[100\,keV\] \[{{E}_{v}}=2.48\,eV\] So, we can say that \[{{E}_{\gamma }}>{{E}_{x}}>{{E}_{v}}\]
