Question

In the photoelectric effect, the strength of the photoelectric current is proportional to

• A. the intensity of the incident radiation
• B. the frequency of the radiation
• C. both the intensity and frequency of the radiation
• D. neither the intensity nor the frequency of the radiation

Answer 1

The correct option is A

the intensity of the incident radiation

The photoelectric current depends on the number of the photoelectrons emitted per second which in turn is proportional to the intensity of the incident radiation.
