Question

Which of the following statements is correct regarding the photoelectric experiment.?

• A. The photo current increases with increase in intensity of light.
• B. Stopping potential increases with increase in intensity of incident light.
• C. The photo current increases with increase in frequency.
• D. All of the these

Answer 1

The correct option is A The photo current increases with increase in intensity of light.

The photocurrent increases linearly with intensity of the incident light, but is independent of its frequency
. The stopping potential increases linearly with the frequency of the incident light, but is independent of its intensity.
