The stopping potential in the context of photoelectric effect depends on the following property of incident electromagnetic radiation:

Options

  1. APhase
  2. BIntensity
  3. CAmplitude
  4. DFrequency

Correct answer

D. Frequency

Step-by-step solution

According to Einstein’s photoelectric equation, stopping potential depends on frequency as h ν - h ν ∘ = e V V = h ν - h ν ∘ e Hence stopping potential depends on frequency.
