From photoelectric effect experiment, select the correct statement.
Options:
Answer:
Solution:
According to the experimental observations of the photoelectric effect:
The photoelectric effect cannot be explained by the wave theory of light; it requires the quantum (particle) nature of light.
The maximum kinetic energy of emitted photoelectrons depends on the frequency of the incident light and the nature of the material, but is independent of the intensity of incident light.
The stopping potential depends on both the frequency of the incident light and the work function of the metal, as given by Einstein's photoelectric equation .
The number of photoelectrons emitted per second is directly proportional to the intensity of the incident light. Therefore, the saturation photoelectric current increases as the intensity of incident light increases.
Answer: The saturation current increases as the intensity of incident light increases.
