Question

The threshold frequency in a photoelectric experiment is most closely related to the
Options
A brightness of the incident light
B thickness of the photoemissive metal
C intensity of the incident light
D work function of the photoemissive metal
Correct Answer
Correct Answer

Option D is the correct answer.

Detailed Explanation

The threshold frequency f₀ is related to the work function φ by φ = hf₀. The threshold frequency is the minimum frequency needed to eject electrons, and it is a property of the metal (its work function).

Hint

The work function is φ = hf₀.
