The photoelectric effect depends upon the photon's
Correct answer: D. Frequency
- A. Pressure
- B. Temperature
- C. Intensity
- D. Frequency
Explanation
The frequency of the light determines the maximum kinetic energy of the emitted electrons. This is because the energy of a photon is proportional to its frequency.

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.
