    The spectrum of radiation \[1.0\times {{10}^{14}}Hz\] is in the infrared region. The energy of one photon of his in joules will be :-

    A)  \[6.62\times {{10}^{-48}}\]        

    B)  \[6.62\times {{10}^{-20}}\]

    C)  \[\frac{6.62}{3}\times {{10}^{-28}}\]         

    D)  \[3\times 6.62\times {{10}^{-28}}\]

    Correct Answer: B

    Solution :

    \[E=hv=6.62\times {{10}^{-34}}\times 1.0\times {{10}^{14}}\] \[=6.62\times {{10}^{-20}}\]  joule
