Light consists of particle wave called:
Correct answer: D. Photon
- A. Proton
- B. Electron
- C. Neutron
- D. Photon
Explanation
The light particle conceived by Einstein is called a photon. Photons exhibit both wave-like and particle-like properties, and they play a crucial role in the quantum theory of electromagnetic radiation.

About Dawn of Modern Physics
Classical physics cannot explain blackbody radiation and related observations, leading to Planck’s quantum theory, in which energy is emitted or absorbed in discrete packets. Photons provide the particle model of light, with energy and momentum linked to frequency and wavelength, including the photoelectric effect and its threshold frequency.
