What is the difference between a 'quantum' and a 'photon'?
Answers
Answer:
In summary, a photon is the tiniest possible particle of light, a quantum of light. A quantum, on the other hand, is the tiniest possible particle of any substance at the subatomic level and includes, for example, electrons and neutrinos.
Answer:
photon is a tiny particle of light. It is the tiniest particle of light possible in nature. A photon can also be described as a type of quantum, that is, a tiny particle. Some other types of quanta (plural) are electrons, neutrinos, and the Higgs boson.
A quantum is the tiniest particle possible of a particular substance. For example, in the case of an electron, it’s the tiniest particle possible of negatively-charged matter, just as a photon is the tiniest particle possible of light.
A quantum is as small as it gets.
