Estimate how many photons per second of visible light
If a 90 lightbulb emits 5.0 of the input energy as visible light (average wavelength 550 ) uniformly in all directions, estimate how many photons per second of visible light will strike the pupil (4.0 diameter) of the eye of an observer 3.0 away.
