In a photoelectric effect experiment, light of a single wavelength is incident on the metal surface. As the intensity of the incident light is increased
A) the stopping potential decreases.
B) the stopping potential increases.
C) the work function decreases.
D) the work function increases.
E) None of these choices are true.

Question

Quizplus · Accepted Answer

The stopping potential and work function are intrinsic properties of the metal surface and are not affected by the intensity of the incident light. Therefore, neither A, B, C, nor D can be true.
