If radio waves and light waves are the same thing, why are radio waves associated with electric currents? ?
Why do electric currents or changing ones emit radio waves so easily as apposed to other EM waves? I've been studying them and I've recently connected how they are all related. But I'm still trying to understand how the waves propagate at the atomic level.
I read that all EM waves travel through photons? Is that true? If so then why are radio waves associated with changing electric currents or electricity in general vs. light?
If you look at a radio antenna, there is nothing coming out of it that you could visibly see, but what about infrared? If you could see in the radio spectrum what would it look like? Would it glow and change colors?
If EM waves are the same phenomena then how I understand it, you get a radio antenna to emit microwaves, then infrared waves, and eventually visible light if you oscillate the current fast enough, is that true? Could we do that?
I meant travel in the form of photons
