Hmm, perhaps my question was not explained well. The detector behind the medium is not in the medium. I know that the wavelength and the velocity will change, but I'm not sure whether the detected phase change will by proportional to time or constant. My confusion is coming from two...

I'm wondering about small changes of phase due to a refractive medium. For example, suppose there is an emitter of radio or light waves, and two detectors equidistant from the emitter. One of the detectors is behind a medium, while the other is a straight shot through a vacuum. How would...

Oh, excellent. I will take a look at those examples. Much appreciated, Simon.

Do those comments apply to the Kerr electro-optic effect? From what I can tell, it's referring specifically to the AC form of it. Do you know where I could find tabulated data for Kerr constants and such? The wiki article mentions a few, such as water (which is what I'm mainly interested in)...

Ah, Simon, that last statement clarifies what I was wondering. Although I am still curious about the question you raised - where does the energy come from? It takes energy to move the charge into that position, so I guess that's where the potential energy comes from? I think where my...

Very interesting, vanhees, that's similar to the kind of idea I was talking about. Why wouldn't such a system indefinitely produce current?

I understand the the motion of charges in a particular direction constitutes a current, and from my understanding, the more charges you have flowing in the same direction, the stronger the current. Are there significantly different properties that arise with strong current? After watching this...

Ok, so to be more specific, I was wondering why those alternating currents would not be produced indefinitely i.e. be in perpetual motion. It's a rather embarrassing question, but it's been nagging at me for some time...Any insights would be much appreciated.

I'm wondering about the Kerr Optical effect as described on wikipedia: http://en.wikipedia.org/wiki/Kerr_effect Are there limits to the range of parameters at which the effect starts to break down? What λ values and E values does this formula apply to?

Hi, I've been toying with a thought experiment, and I was wondering if it had any basis in reality. Is it possible to confine like-charged particles (e.g., primarily positive or primarily negative) to a particular space? After doing some searching, I stumbled upon "non-neutral plasmas", which...
