An adapted human eye (person that has spent 30 min in the dark) can see 1 ms
Question:
An adapted human eye (person that has spent 30 min in the dark) can see 1 ms flashes of power 4×10-14 W at 510 nm with 60% reliability. Assuming that 10% of the incident power reaches the retina, how many photons at the receptors generate the signal that the test person recognizes as flash of light?
