The wavelength corresponding to the maximum sensitivity of the human eye is 510 nm
Can You See a Single Photon? The wavelength corresponding to the maximum sensitivity of the human eye is 510 nm, the limit of sensitivity of the dark-adapted eye has been shown to be correspond to a 100 ms flash of light of total energy 240 eV. (Little Shop of Physics- Colorado State University) 1 J = 6.241509 x 1018 eV
a) What is the energy of a single photon at this wavelength?
b) How many photons does the flash contain?
c) If 60% of the incident light is lost to reflection and absorption by tissues of the eye, determine how many photons reach the retina and if you can see a single photon?
