NEET Physics Photoelectric Effect Assertion Reason Question
Assertion (A): The maximum kinetic energy of photoelectrons is independent of the intensity of incident light. | Reason (R): In the photoelectric effect, each electron absorbs energy from a single quantum of 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 and R is true.
Correct Answer
Detailed Explanation
The maximum kinetic energy is determined by the frequency, not intensity, as each electron absorbs energy from a single photon (quantum).
