The absorbed energy of incident photons is used in two ways: (1) Work Function: part of energy is used to free the electron from metal surface and (Ⅱ) Remaining part is converted to
Correct answer: A. kinetic energy
- A. kinetic energy
- B. potential energy
- C. binding energy
- D. thermal energy
Explanation
Energy of photon = work function + Max. K.E. of photoelectrons hf =Φ+ K.Emax

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.
