NEET Physics Photoelectric Effect MCQ Question
In the diagram shown above, which factor is responsible for the increase in saturation current when the intensity of incident light is increased?
More electrons are emitted per second.
Higher frequency of incident light.
Increased stopping potential.
Decrease in work function of the material.
Correct Answer
Detailed Explanation
Saturation current increases with higher light intensity because more electrons are emitted per second, as stated in the NCERT context. The stopping potential and frequency remain unchanged.
