Field particle of Electromagnetic interaction is _________?
Correct answer: A. Photon
- A. Photon
- B. Meson
- C. Vector Boson
- D. Graviton
Explanation
The electromagnetic interaction is carried by photons, which are massless quantum particles of the electromagnetic field. A vector boson is a general class that includes the photon, but it is not the specific field particle asked for. Students may choose vector boson because the photon belongs to that category.

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.
