Question

Assume that the frequency of the incident light is large enough to overcome the work function, i.e., the photoemission of electrons is already occurring. Does the number of photoelectrons emitted from a metal surface depend on the light intensity?

Answer 1

Yes, the number of photo electrons emitted depends on the light intensity

Step-by-step explanation:

According to Albert Einstein, when light is incident upon a clean metal surface, photo electrons are emitted by the metal surface. By a series of experiments he confirmed that the kinetic energy of emitted photoelectrons depends on the frequency of

incident radiation. However, when the intensity of incident radiation was varied, the number of photoelectrons emitted also varied. This implies that the number of photoelectrons emitted depends on the intensity of incident radiation.
