The stopping potential in the context of photoelectric effect...

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

hν−hν∘=eVV=hν−hν∘ehν - h{ν}_{∘} = eVV = \dfrac{hν - h{ν}_{∘}}{e}

Hence stopping potential depends on frequency.
