How does an accelerating charge radiate electromagnetic waves? [duplicate]

When a charged particle gets accelerated it emits electromagnetic waves. In reality, when a charged particle gets accelerated the electric field around the charge remains unchanged, but the magnetic ...

Why accelerating charged particles radiate EM waves? [duplicate]

Why do they do it? If I apply some constant force on a charged particle, would it gain velocity just like any other particle or would it lose its energy by emitting radiation? What if I observe a ...

Why does an accelerated charged particle emit electromagnetic waves? [duplicate]

Why does an accelerated charged particle emit electromagnetic waves? I have already seen a proof but I am looking for a more intuitive qualitative answer, such as conservation of energy etc. Thank ...

Electromagnetic radiation of charges under accelerations [duplicate]

If we shake a electron back and forth I understand how it radiates electromagnetic wave. But I do not understand how a charge going in circular path or accelerating in a straight line radiates. Please ...

Why do accelerated charges radiate energy? [duplicate]

I have studied the statement that accelerated charges radiate energy and Bohr rectified this issue by introducing concept of stationary states or orbits. But can anyone please tell me why does ...

Why alternating current produces electromagnetic waves? [duplicate]

So my question is: why alternating current produces electromagnetic waves? There are plenty of answers on google that state it as fact, but none answer why. I mean what is it about accelerating ...

How do moving charges produce magnetic fields?

I'm tutoring high school students. I've always taught them that: A charged particle moving without acceleration produces an electric as well as a magnetic field. It produces an electric field ...

Why do atoms (iron eg) glow with all frequencies of light when exposed to enough thermal radiation?

Correct me if I'm wrong, but objects (made of constituent atoms) glow with a particular frequency of light which our eyes relate to as colour. They glow when a particle in a higher energy quantum ...

In an atom, when an electron loses energy, why is a photon released? If photons are massless, how are they created in this process and why?

This is my first question and I am just a 14 year old so excuse me for my mistakes. Please simplify your answer a little only. Using terms thinking I won't understand is a mistake.

Trouble understanding the Bohr model of the atom

In this article it says: The electrons can only orbit stably, without radiating, in certain orbits (called by Bohr the "stationary orbits") at a certain discrete set of distances from the nucleus. ...

How is the energy loss by an accelerating charge expressed in the equations of motion?

I understand how, and why, an accelerating charge emits radiation, and loses energy in the process, as well as the Larmor formula for the power, and its derivation. However, in classical mechanics, ...

No magnetic dipole moment for photon

Electrically neutral particles such as neutrinos can have nonvanishing magnetic dipole moments. Spin-1 particles, e.g., deuterium nuclei, can also have dipole moments. Googling seems to show that the ...

How is light produced?

To be clear here, My question arises from studying Electromagnetic induction and polarisation and photoelectric effect. From here I've gained the knowledge that creation of a photon involves: ...

What causes like electric charges to repel and opposite electric charges to attract at the smallest level?

When talking about charged particles, the law of charge dictates that two particles with opposite charge will attract each other and two particles with the same charge will repel each other. However,...

Are electromagnetic waves only caused by accelerating charges?

Like the title says, are electromagnetic waves only caused by accelerating charges? Are there any other methods for the generation of photons? If electromagnetic waves are ONLY able to be created by ...
