If I were able to tune an RF transmitter at 555THz whould the antena glow green ?

This might sound stupid, but green is in the visible part of the electromagnetic spetrum it should make sense (555THz, ie 540nm, is greenish).
Would it work like that, and, if not, why ? thanks in advance !

Well, yes, if electromagnetic radiation is produced at that frequency, it would look green. In fact, emissive species that radiate green light can to a decent approximation be treated as a classical damped dipole oscillating at that frequency, very similar to a dipole antenna.
