The given graph depicts the phenomenon of
Correct answer: D. Annihilation of matter.
- A. Compton effect.
- B. Pair production.
- C. Photoelectric effect.
- D. Annihilation of matter.
Explanation
The correct answer is annihilation of matter. This process involves the collision of a particle with its antiparticle, leading to their conversion into energy. This is typically depicted in a graph showing energy distribution or photon emission patterns resulting from the process. The other options are incorrect: the Compton effect involves energy and wavelength shifts due to photon-electron interactions, pair production requires photon energy sufficient to create an electron-positron pair, and the photoelectric effect involves electron ejection due to photon interaction with a material surface.

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.
