Quanta vs. Photon: What's the Difference?

Click For Summary
SUMMARY

The discussion clarifies the distinction between "quanta" and "photon" in the context of quantum physics. "Quanta" refers to the smallest discrete units of any physical property, while a "photon" is specifically defined as one quantum of light. This differentiation emphasizes that while all photons are quanta, not all quanta are photons, as the term encompasses various physical properties beyond just light.

PREREQUISITES
  • Understanding of basic quantum physics concepts
  • Familiarity with the concept of quantization in physics

I was reading a book on light and the terms quanta and photon were used for what seemed like the same thing. Whats the differance?

You know, I hope, that in qantum physics quantities are not infinitely divisible but come in "packets". For example, every possible charge is some integer multiple of the charge of an electron. "quantum" (plural "quanta") is the smallest possible amount of whatever quality you are talking about. A photon is specifically one "quantum" of light.
