PhysicsDual Nature of Matter and RadiationJEE Main 2025

Assertion A : In photoelectric effect, on increasing the intensity of incident light the stopping potential increases. Reason R: Increase in intensity of light increases the rate of photoelectrons emitted, provided the frequency of incident light is greater than threshold frequency. In the light of the above statements, choose the correct answer from the options given below

Answer: (4)

Solution

Intensity affects number of photons/photoelectrons, not stopping potential which depends on frequency
