NEET Physics Photoelectric Effect MCQ Question
Which of the following statements about the photoelectric effect is correct?
The stopping potential is dependent on the intensity of incident radiation.
The photocurrent is directly proportional to the intensity of the incident light.
Electrons are emitted only if the frequency of the incident light exceeds a certain threshold frequency.
Increasing the intensity of light increases the maximum kinetic energy of emitted photoelectrons.
Correct Answer
Detailed Explanation
The photocurrent increases linearly with the intensity of incident light, indicating that the number of photoelectrons emitted per second is directly proportional to the intensity (Chunk 3). The stopping potential, however, remains unchanged for a given frequency (Chunk 1).
