I'm quite aware of the dangers and how to avoid them, what about using a simple function generator after wards to modulate the frequency. I just want a high voltage ac that I can modulate the frequency of.

A Neon Sign Transformer

When I plug my NST into the wall at 60 Hz, I've been told a 120 Hz AC current comes out of my NST. What happens if I modulate the input frequency with a function generator to the transformer?

Homework Statement Alright this is from the MIT intro series book by AP French on Waves and Optics, Problem 6-10 (If you happen to have the book) "A laser can be made by placing a plasma tube in an optical presonany caity formed by two highly reflecting faltmirrors, which act like rigid...

Bump!

As in allowing the light to be scattered by flour in the air?

Alright, I've been looking around for an opinion on this for awhile: Suppose you have a tube of deuterium whose radius is much much less then the length. You use a high voltage/large current to ionize this Deuterium. In a similar configuration to the Z-Pinch device a magnetic field is...

IMHO, Wikipedia is a great source because it gives you what you need to get to certain equations, but doesn't give you the steps in between--you can prove them yourself. I feel Wiki is accurate enough for math, maybe not for other subjects.

Homework Statement What would the geometric explanation of exp(-i*x) be? Homework Equations Exp(-i*x), i being (-1)^1/2 The Attempt at a Solution I'm pretty sure this is just a circle, created clockwise? Just want to check.
