A photon is a:
Correct answer: B. Quantum of electromagnetic radiations
- A. Unit of energy
- B. Quantum of electromagnetic radiations
- C. Positively charged particle
- D. Unit of wavelength
Explanation
Potons are the bundles of energy are integral part of electromagnetic radiations and they could not be sub divided. It does not exist at rest. So, its rest mass is zero

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.
