In a photoelectric effect experiment, the stopping potential depends on which of the following?
- A.Intensity of incident light
- B.Frequency of incident light
- C.Time of exposure
- D.Distance of source
Show correct answer & step-by-step solution
Correct answer: B — Frequency of incident light
Solution
According to Einstein photoelectric equation, the maximum kinetic energy of emitted electrons depends on the frequency of the incident light. Since stopping potential is directly related to maximum kinetic energy, it also depends on the frequency.
