What is the quantum of an electromagnetic wave? Quantum of light is photon. What is the quantum of a gamma ray or an X-ray?
 
Physics news on Phys.org
Light is electromagnetic energy. Visible light is a particular part (i.e: another frequency) of the electromagnetic spectrum. There is plenty of information on the internet.
 
I am aware of the fact that visible light is an electromagnetic wave. Just like quantum of light is photon, what is the quantum of gamma ray or X-ray?
 
Visible light is an electromagnetic wave. Gamma ray is an electromagnetic wave. X-ray is an electromagnetic wave. UV is an electromagnetic wave. IR is an electromagnetic wave. RF is an electromagnetic wave.

Thus, they all also have photons.

Zz.
 
A gamma ray is a type of electromagnetic radiation/energy. X-rays are as well.
 
Not an expert in QM. AFAIK, Schrödinger's equation is quite different from the classical wave equation. The former is an equation for the dynamics of the state of a (quantum?) system, the latter is an equation for the dynamics of a (classical) degree of freedom. As a matter of fact, Schrödinger's equation is first order in time derivatives, while the classical wave equation is second order. But, AFAIK, Schrödinger's equation is a wave equation; only its interpretation makes it non-classical...

Is it possible, and fruitful, to use certain conceptual and technical tools from effective field theory (coarse-graining/integrating-out, power-counting, matching, RG) to think about the relationship between the fundamental (quantum) and the emergent (classical), both to account for the quasi-autonomy of the classical level and to quantify residual quantum corrections? By “emergent,” I mean the following: after integrating out fast/irrelevant quantum degrees of freedom (high-energy modes...
