Under controlled darkened conditions in the laboratory, a light receptor cell on the retina of a person's eye can detect a single photon of light of wavelength 503nm and having an energy of 3.84×10?19J . We shall assume that this energy is absorbed by a single cell during one period of the wave. Cells of this kind are called rods and have a diameter of approximately 2.0×10?3mm .

a. What is the intensity in (W/m^2) delivered to a rod? express your answer using 2 sig figs. in w/m^2.
