NEET Physics Photoelectric Effect MCQ Question
Which of the following combinations about the photoelectric effect is correct?
The photocurrent increases with intensity, and the threshold frequency is unique to each material.
The photocurrent does not depend on the intensity of light, and stopping potential varies with intensity.
Electrons are emitted regardless of light frequency, and only ultraviolet light can cause photoemission.
The intensity has no effect on the number of emitted electrons, and stopping potential is independent of emitter material.
Correct Answer
Detailed Explanation
The photocurrent is directly proportional to the intensity of light, and the threshold frequency varies for different materials, as mentioned in the provided context.
