The frequency of the incident photon after Compton effect will:
Correct answer: C. Decrease
- A. Remain constant
- B. Increase
- C. Decrease
- D. None of these
Explanation
The energy of photons is directly proportional to their frequency and inversely proportional to their wavelength, so lower-energy photons have lower frequencies and longer wavelengths. Therefore, frequency of incident photon after compton effect will decrease. Therefore, option C is correct.

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.
