From the photoelectric effect experiment, following observations are made. Identify which of these are correct. A. The stopping potential depends only on the work function of the metal. B. The saturation current increases as the intensity of incident light increases. C. The maximum kinetic energy of a photo electron depends on the intensity of the incident light. D. Photoelectric effect can be explained using wave theory of light. Choose the correct answer from the options given below:
- A, B, D only
- A, C, D only
- B only
- B, C only
Correct answer: B only
Solution
Option B is correct because the stopping potential is determined by the work function and the energy of the incident photons, not the intensity. The saturation current does increase with light intensity, and the maximum kinetic energy of photoelectrons is independent of intensity, relying instead on the frequency of the light.
