Which is the elementary quantum of energy?
Which is the elementary quantum of energy?
- A. Photon
- B. Electron
- C. Proton
- D. Neutron
Step-by-step solution
In quantum physics, energy is quantized, and the photon is the fundamental quantum of electromagnetic energy. It represents the smallest discrete amount of light or other electromagnetic radiation. Electrons, protons, and neutrons are particles with mass and are not considered quanta of energy in the same sense.
