Question

In photoelectric effect, the photoelectric current

Options

• Increase when frequency of incident photons increase

• Decrease when frequency of incident photons increase

• Does not depends on photon frequency but only on intensity beam.

• Depends both on intensity and frequency of incident beam.

Answer 1

Increase when frequency of incident photons increase

Explanation:

Photoelectric current is only affected by the intensity of incident light and is unaffected by the frequency of incident light.
