I know that the secondary coil used in the Tesla coil radiates electromagnetic waves in the surroundings. This radiation makes the electrons in the fluorescent material of the light oscillate, and they emit photons.
My question is,
Does this oscillating electromagnetic field (i)excite the electrons in the fluorescent material directly, or (ii)does it excite the gas to emit UV, which in turn, excite the fluorescent material?
Tesla coils generate an electromagnetic field with frequency in the radio wave region. If (i) (in Q1) is true, then how does low-frequency radio waves excite the fluorescent material to emit visible light (of higher frequency)?
If (ii) is true, then how can radio waves excite gas molecules to generate UV?
- If (i) is true, then can we use Tesla coil to excite proteins with fluorescence tag, or proteins like Green Fluorescent Protein, so that they emit without any light of higher frequency exciting them? (Actually, in case (i) is true, I want to do this experiment, that's why I am asking)
