![]() The ionized electrons are then accelerated and ionize further atoms. ![]() These electrons pick up enough energy before they collide with another gas atom that they ionize that gas atom. What actually happens is that the near electric field from the Tesla coil accelerates any free electrons in the tube's low pressure gas. A 1 MHz radio photon ( $h\nu=4\times 10^eV$) is also way too low in energy to ionize an atom which requires ~10 eV. The radio frequency photons emitted by a Tesla coil are much too low energy to directly excite atoms to emit visible (~2 eV) or UV photons (~6 eV). 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).If (ii) is true, then how can radio waves excite gas molecules to generate UV? If (i) (in Q1) is true, then how does low-frequency radio waves excite the fluorescent material to emit visible light (of higher frequency)? ![]() Tesla coils generate an electromagnetic field with frequency in the radio wave region. This radiation makes the electrons in the fluorescent material of the light oscillate, and they emit photons.ĭoes 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? I know that the secondary coil used in the Tesla coil radiates electromagnetic waves in the surroundings. ![]()
