The photoelectric threshold frequency depends upon:
Correct answer: B. nature of material
- A. Frequency of incident light
- B. nature of material
- C. Intensity of incident light
- D. Frequency of light and nature of material
Explanation
The threshold frequency depends upon the nature of the metal. It is different for different metals.

About Photons and the Particle Model of Light
The particle model treats light as photons with energy E equals hf and momentum related to wavelength. Questions involve the photoelectric effect, work function, threshold frequency, stopping potential and photon energy, while distinguishing particle behaviour from the wave description of interference and diffraction.
