Question
The threshold frequency in a photoelectric experiment is most closely related to the
Correct Answer
Option D is the correct answer.
Detailed Explanation
The threshold frequency (f₀) is the minimum frequency of incident radiation required to eject electrons from a metal surface. It is directly related to the work function (φ) of the metal by the equation φ = hf₀. A higher work function implies a higher threshold frequency.
Hint
Consider the minimum energy required to liberate an electron from the surface of a metal.
