Photoelectric Experiment: Intensity, Stopping Potential & Graphs

In a photoelectric experiment, if the intensity of incident light is doubled and the frequency is kept slightly greater than threshold frequency, then the saturation photoelectric current

Show answer and solution

Answer: (c)

  1. Above threshold, saturation current ∝\propto number of photons per second ∝\propto intensity.
  2. Doubling intensity doubles the current.
  3. So the answer is (c) is doubled.
