Photoelectric Experiment: Intensity, Stopping Potential & Graphs

The stopping potential of the photoelectrons, from a photo cell is

Show answer and solution

Answer: (b)

  1. V0=heν−ϕeV_0 = \dfrac{h}{e}\nu - \dfrac{\phi}{e}: V0V_0 increases linearly with frequency and does not depend on intensity.
  2. Of the given options, only (b) relates V0V_0 to frequency in the right direction (strictly it is linear, not exactly proportional).
  3. So the answer is (b).
