Type: MCQ-fact-Medium-Class 12
What is the effect on photoelectron emission when the frequency of incident light is below the threshold frequency?
A
No photoelectrons are emitted.
B
Photoelectrons are emitted with maximum energy.
C
Photoelectrons are emitted with reduced energy.
D
Photoelectrons are emitted instantly.
Correct Answer
Option A
Detailed Explanation
For frequencies less than the threshold frequency, no photoelectrons are ejected, as stated in the text. This indicates that the energy provided by the photons is insufficient to overcome the work function of the metal.
