NEET Physics Photoelectric Effect MCQ Question
What happens to the photoelectric current when the intensity of incident light is increased while keeping the frequency constant?
The photocurrent increases linearly with intensity.
The photoelectric current decreases with intensity.
The photoelectric current remains constant regardless of intensity.
The photocurrent becomes zero at higher intensities.
Correct Answer
Detailed Explanation
The photocurrent increases linearly with intensity, indicating that the number of photoelectrons emitted per second is directly proportional to the intensity of the incident light, as stated in the NCERT context.
