Question

Quizplus · Accepted Answer

The photoelectric effect states that the number of electrons ejected from a photosensitive surface is directly proportional to the intensity or brightness of the illuminating light. Therefore, the brighter the light, the more electrons will be ejected. The velocity of ejected electrons, however, depends on the energy of the incident photons and not on the brightness of the light.
