Hi all

let suppose a charge is in oscillating (e.g antenna),it broadcast wave,and also suppose an observer oscillate , so the observer had saw the charge in fixed distance so we have not magnetic field.

what we could say about the energy that the observer recived?

The oscillating charge will still radiate.

Thanks
But I could not understand your sentence,
finally the observer will see the wave or not?

That observer will still see an oscillating E field. But we need to be careful E and B fields in accelerated reference frames. And don't take anything i say to literally

I also don't understand;Whay should "That observer will still see an oscillating E field ?" when the charge and Observer are in a constant distance?
