The photon is the particle which has:
Correct answer: C. No rest mass & no charge
- A. Infinite rest mass
- B. Rest mass but no charge
- C. No rest mass & no charge
- D. A & C are correct
Explanation
A photon is simply a quantized particle of light and so has no rest mass nor charge.

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.
