Question

How does the intensity of the incident radiation affect photoelectric effect?

• A. As the intensity increases, photoelectric effect may increase
• B. As the intensity increases, photoelectric effect decreases.
• C. As the intensity decreases, photoelectric effect increases.
• D. No effect

Answer 1

The correct option is A As the intensity increases, photoelectric effect may increase

As the intensity of light increases the number of photons striking the surface will increase.
If frequency of incident radiation is more than thresold frequency then photoelectric effect will increase and if it is less than frequency of incident radiation then photoelectric will not be observed even after increasing the intensity.
