A beam of light having frequency greater than the threshold frequency shines on a metal surface.By increasing the intensity of this light,you increase the number of photoelectrons emitted per second from this metal.

Question

Quizplus · Accepted Answer

According to the photoelectric effect, the intensity of light determines the number of photons incident on the metal surface, but it does not affect the energy of individual photons. So, by increasing the intensity, the number of photoelectrons emitted per second increases, but not their individual energies.
