What causes the the windows to vibrate (what is the resonance, a match between the frequency to density/somethinelse?), assuming that it is in the range where no extinction occurs?

Hi, Quick question (sort of): Say that a car passes in the hood in a street near your house, it's speakers booming Mozart. At first, you only hear the muffled sounds, but as the car comes into a certain range not only you hear it clearly, but your window vibrates. Since this changes with...

Well being no expert either, I do think the Townsend discharge and Paschen's law to be an explanation, unless someone know's better. There's a relation to pressure and to the breakdown voltage of gasses, which is the voltage in which the pretty electric arc is formed between the two electrodes...

Thanks a lot! I will look for illumination and conductance characteristics to further educate myself. Again, thanks!

Not quite sure what you mean by "understand the concept of leak detection in general". While the device I'm referring to is used to detect leaks in vacuum systems, my question is about the how. Tesla coils ionizes the air in the vacuum system alone, not the air under STP (or if you wish, under...

Thanks, but that still doesn't answer. Yes, it ionizes the air in the vacuum system which is at lower pressure. I wrote it as well. Looking at ionization equations it has nothing to do with pressure, and although the model is a theoretical one, I do believe there's a more grounded explanation...

It does, I used it, I just didn't know that's what it was. Tesla coil is used to detect leaks in vacuum systems, here's also a reference. http://books.google.co.il/books?id=EXFeF62iL64C&pg=PA21&redir_esc=y#v=onepage&q&f=false The reference doesn't answer the important question, which is why...

Why does Tesla coil detects vacuum leaks?

Hello everyone, Since it is well as established that time moves slowly as the velocity approaches light-speed, what happens when velocity "aspires" (not sure this is the correct phrase, as I'm translating directly from my native language) to an absolute zero? If there's a formula or another...
