NEET Physics Photoelectric Effect MCQ Question
What is the cut-off frequency in the context of the photoelectric effect?
The minimum frequency below which no photoelectric emission occurs
The maximum frequency that can cause photoelectric emission
The frequency at which photoelectric emission is at its peak
The frequency of light that produces the most kinetic energy in photoelectrons
Correct Answer
Detailed Explanation
The cut-off frequency, also known as the threshold frequency, is defined as the minimum frequency below which no photoelectric emission is possible, regardless of the intensity of the incident radiation.
