NEET Physics Photoelectric Effect Assertion Reason Question
Assertion (A): The stopping potential is independent of the intensity of incident light.
Reason (R): The stopping potential is directly related to the maximum kinetic energy of emitted electrons, which depends on the frequency of incident light.
Both A and R are true and R is the correct explanation of A.
Both A and R are true but R is not the correct explanation of A.
A is true but R is false.
A is false but R is true.
Correct Answer
Detailed Explanation
The stopping potential depends on the frequency of the incident light and is independent of its intensity. The maximum kinetic energy of emitted electrons, which is related to the stopping potential, is determined by the frequency and not the intensity.
