- #7-aWhat is the energy per photon associated with the sodium light? (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.
