For how long must light be emitted for a human eye to perceive it? - Would a person notice a flash of light that lasted 10 ms? - Does the intensity of the light matter? - How much light is a photon, anyway? Does is take thousands or trillions of photons interacting with the eye to register as light? 1am where I live and I’m wondering
