B How is light related to charged particles?

  1. Jul 9, 2018 #1
    I did a little more research, please clarify. So the electric field is directed to the proton and that emits light? Can you get into more detail?

    I am not educated in math so this is hard to understand at this point. I understand how electrons emit light but not protons. So is the magnetic field directed to the electrons while the electric field is directed to the proton? This is hard to visualize in terms of space, because Inwould imagine both the electric field would be different compared to how they’re oriented. I just need more detail.

    So the only atoms that emit light are charged particles? What about electrons?

    What do you mean by ”directed to the proton”?

    It is not about emitting light. Planets do not emit light and they are made of normal matter. It is about interacting with light and that is, by definitiom, what charged particles do.

    I’m no mathematician so I am confused about how the electromagnetic field is oriented in space. There is the electric field then the magnetic that are unified as far as I know. Wouldn’t the electric field and magnetic field be permeating through all of space? Is the idea the magnetic and electric field being “perpendicular” in space just an abstraction to explain it? Wouldn’t not all of the protons and electrons not be hitting all the light? My question is hard for me to explain, Id like help.

    Your approach here is not constructive. Instead of pouring out all your thoughts simultaneously, I would suggest that you focus on one issue per thread.
    Yes, they exist everywhere. However, the force on a charged particle depends only on the field values where it is.

    They do not need to be perpendicular. However, they are perpendicular in the plane wave solutions for electromagnetic radiation in free space.

    It is unclear what you mean by "hitting all the light". I suggest you take some time to really think about what it is that you want to ask and formulating it in a concise manner.
