NEET Physics Photoelectric Effect MCQ Question
Which of the following statements about the photoelectric effect is correct?
The maximum kinetic energy of emitted photoelectrons increases with the intensity of incident radiation.
Increasing the frequency of radiation at a fixed intensity can increase the number of emitted photoelectrons.
The stopping potential remains constant when the intensity of the incident radiation is varied, at a fixed frequency.
Photoelectric current is independent of the intensity of the incident light when frequency is constant.
Correct Answer
Detailed Explanation
The stopping potential is independent of intensity for a given frequency, as noted when varying the intensity while observing constant stopping potential. Increasing intensity only increases the number of emitted electrons.
