NEET Physics Photoelectric Effect Assertion Reason Question
Assertion (A): For a given frequency of incident radiation, increasing the intensity of light increases the number of photoelectrons emitted per second.
Reason (R): The stopping potential is dependent on the intensity of the incident radiation.
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 assertion is true because the photocurrent increases with the intensity of light, meaning more photoelectrons are emitted. However, the reason is false because the stopping potential is independent of the intensity of light.
