AIPMT PRELIMS 2009 Physics Einstein's Photoelectric Equation MCQ Question
Type: MCQ-conceptual-Medium-Class 12
The number of photo electrons emitted for light of a frequency ν (higher than the threshold frequency ν₀) is proportional to:
A
Threshold frequency (ν₀)
B
Intensity of light
C
Frequency of light (ν)
D
ν − ν₀
Correct Answer
Option B
Detailed Explanation
The number of photoelectrons emitted is directly proportional to the intensity of light, as intensity determines the number of photons striking the surface.
