What do we know about the radiation emitted by an oscillating charge ? Anyone care to share their wisdom ?

Thanx guys ... appreciate it.
I downloaded the textbook by Bo Thidé and searched it for the word "doppler". It didn't find anything. This confirms my belief that the classical description of the radiation from an oscillating charge is incomplete, because it obviously experiences dopplereffect (as can be seem in the applet).
I'm I way of here or what ? SHould I be searching for soething else ?
Yup, you're off -- the classical description uses Maxwell's equations, which have all the wave properties, including not just classical 'Doppler' effects but relativistic ones as well.Originally posted by Hydr0matic

I wouldn't say next door, but at least in the same countryHow about that! You are in Malmo and almost next door to you in Uppsala there is Bo T who has made maybe the best online Classical Electrodynamics book.
Have a look at this shockwavefilm of an oscillating charge ... It shows the dopplereffect I'm talking about below.What was happening that caught your attention and made you say:
"because it obviously experiences dopplereffect (as can be seen in the applet)"?
Yes, this is indeed what I'm talking about. Let me show you both what I mean...What exactly do you mean by the "doppler effect" here? Usually it is used to refer to frequency changes due to relative motion between a source and observer.
No, not very often; once in a while there's an OK movie produced, but in general - they all suck .BTW do you ever watch Scandinavian films?

PS.
You're right, this thread now belongs in the theory development forum.
And yes, I know this idea is very crackpotish.
DS.
I agree, the appearence of my concept of doppler is wacko. Unfortunately for me, there is no "electromagnetic fields"-tool i photoshop, and I don't feel like spending hours trying to replicate one, so please give me a break . I must not have given the impression of knowing very much about physics , but trust me, I'm familliar with the concept of doppler.Your concept of doppler is totally wacko, in my opinion, but this is all right. Do not apologize. Your pictures ABC and D are not what the field would do---they are tracings of the motion the particle on a moving strip of paper and do not represent the field. I am not going to argue about this.
That's because it wasn't directed specifically at you, but for anyone reading this thread thinking it does not belong here.I certainly never said that this thread belongs in Theory Development! I do not understand your PS
An oscillating charge refers to an electric charge that is moving back and forth or vibrating at a certain frequency. This movement of the charge creates an electric field and a magnetic field, which results in the emission of electromagnetic radiation.
Radiation emitted by an oscillating charge refers to the electromagnetic waves that are produced as a result of the movement of the charge. These waves carry energy and can travel through space, transferring energy from the oscillating charge to other objects or particles.
The movement of an oscillating charge creates an electric field and a magnetic field, which together produce electromagnetic radiation. The frequency of the radiation is directly related to the frequency of the oscillating charge. As the charge oscillates faster, the frequency of the radiation also increases.
The energy of the radiation emitted by an oscillating charge is directly proportional to the energy of the charge itself. This means that as the charge increases in energy, the radiation it emits also increases in energy. This relationship is described by the equation E=hf, where E is the energy of the radiation, h is Planck's constant, and f is the frequency of the radiation.
Oscillating charges and the radiation they emit are used in various technologies, such as radio and television broadcasting, wireless communication, and medical imaging. They are also important in astronomy, as the radiation emitted by oscillating charges in stars and other celestial bodies can provide valuable information about their properties and behavior.
