Which of the following options represent the variation of photoelectric current with the property of light shown on the x-axis?
Show Hint
Remember the key laws of the photoelectric effect:
1. Photoelectric emission occurs only if the frequency of incident light is above a certain threshold frequency.
2. The photoelectric current is directly proportional to the intensity of incident light (for a frequency above the threshold).
3. The kinetic energy of the emitted photoelectrons depends on the frequency of incident light and is independent of the intensity.
