Which of the following predictions of the classical wave model of light (Maxwell's EM theory) were contradicted by the observations during the photoelectric effect experiment?
Which of the following predictions of the classical wave model of light (Maxwell's EM theory) were contradicted by the observations during the photoelectric effect experiment?
The correct options are
B For a moderate to high intensity, there will be some photocurrent no matter what the frequency is.
C Increasing intensity of light while keeping the frequency constant will result in a higher (more negative) stopping potential.
D Keeping the intensity fixed, changing the frequency should not affect the stopping potential at all.
The wave theory failed in epic proportions when it came to predicting the observations of the photoelectric effect. As we saw, all but prediction (a) were contradicted by the observations made during the experiment. Observations were in complete disagreement with (b), (c), and (d).
