Question

In a photoelectric effect experiment if the frequency is above the threshold frequency, then the number of electrons ejected is proportional to:

• A. their kinetic energy.
• B. the work function.
• C. the frequency of the incident light.
• D. the number of photons that hit the sample.

Answer 1

The correct option is D the number of photons that hit the sample.

The number of photos that hit the sample

The number of electrons ejecting depends on the number of photons striking the plate per second.
