So what does a single photon do to a group of charged particles?

In summary, the conversation discusses the characteristics of photons and how they interact with other charged particles. The question of whether the electric and magnetic fields pulsate in a spherical way and if this affects the movement of particles is raised, but it is noted that this concept may not be entirely accurate as photons are quantum objects and do not have an extended set of fields.

I have heard, but never seen a representation, that we know the characteristics of photons because of their reaction with other charges particles. So what exact physical motions are induced on the particles when a photon travels through them. Does the magnitude of the electric and magnetic fields pulse in a spherical way, so the particles may move in a uniform way from the photon, the distance of the radius depending on the strength of the fields? Does this make sense?

Does this make sense?
No it does not. We are really developing an extensive mythology here! As pointed out elsewhere, a photon is a quantum object. It is not accompanied by an extended set of E and B fields. When it interacts, it collides with a single particle and is absorbed by it. The energy it had goes into kinetic energy of the struck particle and also possibly creating other particles.
 

1. What is a single photon?

A single photon is the smallest unit of light and carries energy in the form of electromagnetic radiation.

2. How does a single photon interact with charged particles?

A single photon can interact with charged particles through the process of absorption, scattering, or emission. In absorption, the photon transfers its energy to the charged particle. In scattering, the photon changes direction after interacting with the charged particle. In emission, the charged particle releases energy in the form of a photon.

3. Can a single photon affect a group of charged particles?

Yes, a single photon can affect a group of charged particles through the process of scattering. When a photon interacts with one charged particle in the group, it can cause a chain reaction of scattering among the other particles, affecting the overall behavior of the group.

4. What factors influence the interaction between a single photon and a group of charged particles?

The interaction between a single photon and a group of charged particles is influenced by several factors, including the energy and wavelength of the photon, the distance between the photon and the particles, and the properties of the individual charged particles such as their charge and mass.

5. What are the applications of studying the interaction between a single photon and a group of charged particles?

Studying the interaction between a single photon and a group of charged particles can have various applications in fields such as optics, quantum mechanics, and astrophysics. It can also help us understand fundamental properties of matter and develop new technologies such as quantum computing and telecommunications.
