Antennas work with variable current that leads to accelerations and deceleration ofor the electrons, the frequency of the photon or the electromagnetic radiation I want to generate depends on the change in kinetic energy of the electron E= hf= change of kinetic energy of the electron, according to bremsstrahlung and electromagnetic radiation can be created without an harmonic motion of the charge we are considering
So if we create an antenna that makes electrons undergoing harmonic motion we will get that the change in kinetic energy will be 1/2 m w^2 A^2
So hf= 1/2 m w^2 A^2
Andi know that is wrong cos I know that the frequency of the emited wave is equal to the frequency of the harmonic motion of the electrons, but Why?
Also seems logical that is equal to the frequency of the electrons because the electric field oscillates with that frequency but where is the mistake I made?
I mean the frequency of the photons emited by the electrons doesn't depend by the frequency the electrons were oscillating but the change in kinetic energy of those no?
How can I connect the quantum mechanics relation E= hf and the bremsstrahlung correctly to the antenna fenomenon? Please help, this is driving me crazy
