In photoelectric effect, for incident light above the threshold frequency, the saturation photocurrent
Options:
Answer:
Solution:
In the photoelectric effect, the saturation photocurrent is determined by the total number of photoelectrons emitted per second from the photosensitive surface.
According to the laws of photoelectric emission, for incident light above the threshold frequency, the number of photoelectrons emitted per second is directly proportional to the intensity of the incident light (which corresponds to the number of incident photons per unit area per unit time).
The frequency of the incident light determines the maximum kinetic energy of the emitted photoelectrons and the stopping potential, but it does not affect the number of photoelectrons emitted per second.
Therefore, the saturation photocurrent does not depend on the frequency of the incident photon but depends only on the intensity of the incident light.
Answer: does not depend on the frequency of photon but depends only on the intensity of incident light.
