NEET Physics Photoelectric Effect Assertion Reason Question
Assertion (A): The stopping potential for photoelectric emission is independent of the intensity of incident light. | Reason (R): Photoelectrons are emitted with a kinetic energy that depends only on the frequency of the incident radiation and not on its intensity.
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 is independent of intensity because it is related to the maximum kinetic energy of photoelectrons, which only depends on the frequency of the incident light, not its intensity, as explained in Chunk 2 and 3.
