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 {\rm nm} and having an energy of 3.94Γ10-19 {\rm 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 2.00Γ10-3 {\rm mm}.
