Maximum kinetic energy of photoelectrons depends upon_of incident light.
Correct answer: A. Frequency
- A. Frequency
- B. Brightness
- C. Intensity
- D. Power
Explanation
In photoelectric effect the electrons are emitted with different energies. The maximum energy of photoelectrons depends on the nature of metal surface and the frequency of incident light.

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.
