    What will be the number of photons emitted per second by a 10 W sodium vapour lamp assuming that 90% of the consumed energy is converted into light [Wavelength of sodium light is 590 nm. and \[y=6.63\,\times {{10}^{-34}}J-s\]]

    A)  \[0.267\,\times {{10}^{18}}\]                    

    B)  \[0.267\,\times {{10}^{19}}\]       

    C)             \[0.267\,\times {{10}^{20}}\]    

    D)         \[0.267\,\times {{10}^{17}}\]

    Correct Answer: C

    Solution :

    Energy of photon, \[I\] \[I\] \[I\] Light energy produced per second \[\overset{0}{\mathop{A}}\,\] Number of photons emitted per sec \[\overset{0}{\mathop{A}}\,\]
