    Excited hydrogen atom emits light in the ultraviolet region at\[2.47\times {{10}^{15}}Hz\]. With this frequency, the energy of a single photon is: \[(h=6.63\times {{10}^{-34}}Js)\]

    A) \[8.041\times {{10}^{-40}}J\]               

    B) \[2.680\times {{10}^{-19}}J\]

    C) \[1.640\times {{10}^{-18}}J\]    

    D) \[6.111\times {{10}^{-17}}J\]

    Correct Answer: C

    Solution :

    [c] \[E=hv\] \[=6.63\times {{10}^{-34}}\times 2.47\times {{10}^{15}}\] \[=1.640\times {{10}^{-18}}J\]
