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.
 
Insights auto threads is broken atm, so I'm manually creating these for new Insight articles. Towards the end of the first lecture for the Qiskit Global Summer School 2025, Foundations of Quantum Mechanics, Olivia Lanes (Global Lead, Content and Education IBM) stated...

If we release an electron around a positively charged sphere, the initial state of electron is a linear combination of Hydrogen-like states. According to quantum mechanics, evolution of time would not change this initial state because the potential is time independent. However, classically we expect the electron to collide with the sphere. So, it seems that the quantum and classics predict different behaviours!
