Under ideal conditions, a visual sensation can occur in the human visual system if light of wavelength 550 nm is absorbed by the eye’s retina at a rate as low as 100 photons per second.What is the corresponding rate at which energy is absorbed by the retina?
The threshold of dark-adapted (scotopic) vision is 4.0 × 10−11 W/m2 at a central wavelength of 500 nm. If light with this intensity and wavelength enters the eye when the pupil is open to its maximum diameter of 8.5 mm, how many photons per second enter the eye?
