JEE Main 2025 Physics question
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
