Synchrotron radiation and conservation of energy

[varga]

a) What is this Maxwell equation everyone is talking about?
======================

Oh my goodness! After all this debacle and a thread this lengthy, we now have a confirmation that you really don't know what you're discussing?

Unless the OP has lingering question related to the original question, I think this thread is going nowhere fast because we keep having to make several steps back to explain basic physics. If you don't understand basic E&M (i.e. these "Maxwell equations"), then we'd be more than happy to answer specific questions on it. This is not the way to do it.

Questions on the origin of "spin" and magnetic moment of atoms have been answered in many other threads in the Quantum Physics forum. One is welcomed to do a quick browse.

This thread is done.

My question is "stupid"?

I do have very specific questions and I accept your invitation to ask them...

- "electrodynamics (i.e. Maxwell's equations) describes radiation from charged particles accelerating in a Coulomb field."

So I was asking him which one of the FOUR Maxwell's equations is he talking about. What is wrong with that? And, would you mind answering the question as you offered?


Rest of the questions:
- 'Electronvolt' was calculated and experimentally confirmed according to Coulomb's law equation or some other equation?

- Do you think anyone would label Coulomb force as "conservative force" if they knew there was any loss of energy there?

a) DECELERATION: does it slow down BECAUSE it radiates, or it radiates because it slows down?
b) ACCELERATION: does it speed up BECAUSE it radiates, or it radiates because it speeds up?
====================

These make no sense. Both are easily answered because if it radiates BECAUSE it speeds up, it is violating the conservation of energy. Or is that something you question as well?

If it radiates because it slows down, then it is violating causality because it is doing something on its own...

SpectraCat said:
- "an accelerating charge emits light, whether it is slowing down or speeding up."


You say:
- "Electron radiates because it speeds up", is WRONG.
- "Electron radiates because it slows down", is WRONG.

So, does that leaves us with:
- Electron speeds up because it radiates. (CORRECT ?)
- Electron slows down because it radiates. (CORRECT ?)


Can you clarify,
Thank you

1. How about you ask one question at a time?

2. The majority of this has nothing to do with quantum mechanics. What you're asking is classical E&M (and thus, this thread will be moved to the appropriate forum).

3. Accelerated charges radiates. This is classical electrodynamics. Electrons speeding up or slowing down radiates. Which part of this do you dispute based on current physics?

Zz.
