    What is the energy per photon associated with the sodium light? (b) At what rate are the photons delivered to the sphere?
    (b) At what rate are the photons delivered to the sphere?
    Ans : The energy per photon associated with the sodium light is given as:




    (b) Number of photons delivered to the sphere = n

    The equation for power can be written as:



    Therefore, every second, photons are delivered to the sphere.
    (b) Number of photons delivered to the sphere = n

    The equation for power can be written as:



    Therefore, every second, photons are delivered to the sphere.
