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 505 nm and having an energy of 3.94×10-19 J. 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 2.00×10-3 mm

What is the intensity (in W/m^2) delivered to a rod?
