Physics-Photoelectric Effect
NEET Physics Photoelectric Effect MCQ Question
Type: MCQ-diagram based-Hard-Class 12
Consider a metal surface exposed to monochromatic light, resulting in photoelectric emission. If the intensity of the light is increased while keeping the frequency constant, which of the following changes will occur in the photoelectric current?
A
The photoelectric current will increase.
B
The photoelectric current will decrease.
C
The photoelectric current will remain constant.
D
The photoelectric current will first decrease then increase.
Correct Answer
Option A
Detailed Explanation
According to the photoelectric effect, the photoelectric current depends on the intensity of the incident light. Increasing the intensity will increase the number of emitted electrons, thus increasing the current.
