Kinetic energy and stopping potential are zero, when frequency of incident radiation is equal to three (high).
Explanation:
- For a fixed frequency of incident radiation, the photoelectric current increases linearly with increase in intensity of incident light.
- Different values of stopping potential are obtained but the same value of the saturation current for incident radiation of different frequencies.
- The energy of the emitted photo electrons is thus seen to depend on the frequency of the incident radiations.
- The stopping potential is more negative for higher frequencies of incident radiations.
- Greater the frequency of incident radiations, greater is the maximum kinetic energy of the photo electrons.
- That is why a greater retarding potential is required to stop them completely.
