NEET Physics Photoelectric Effect MCQ Question
Type: MCQ-diagram based-Easy-Class 12
Consider a diagram where a beam of light falls on a metal surface causing the emission of electrons. Which of the following factors affects the maximum kinetic energy of the emitted photoelectrons?
A
The frequency of the incident light
B
The intensity of the incident light
C
The material of the collector plate
D
The size of the metal surface
Correct Answer
Option A
Detailed Explanation
The maximum kinetic energy of the photoelectrons is affected by the frequency of the incident light, as explained by Einstein's photoelectric equation. The stopping potential depends on the frequency, not the intensity.
