frequency - What happens if I tap my hand at visible light frequencies?

I have never taken a formal physics course, yet, so I apologize if my question is elementary.

I have seen electromagnetic charts where it shows a single digit Hz up to gamma rays etc each with their associated frequency range. My question is, what determines if something is light at a said frequency. For example, if I tap my hand at a visible light frequency my hand will not turn to light, at least I do not think so. If a frequency can be associated with a phenomenon like light or sound, that does not mean simply anything made to oscillate at that frequency will manifest itself into that phenomena.

So is there a chart that shows what materials will produce a specific thing like light at light frequencies?. Again I have no formal physics training, so if you can answer keeping that in mind. it would be of great service to me.

Answer

The frequency of visible light is about $500\times10^{12}$Hz, five hundred trillion oscillations per second. I believe that if you could tap your hand at this frequency, it would give off visible light, as well as disintegrating. It would be very hard indeed to oscillate any macroscopic body at that frequency though. I don't believe that such technology exists. All of the common kinds of visible light such as incandescent light bulbs, LEDs, fluorescent tubes, and sunlight are given off by the motions of microscopic charged particles called electrons rather than by macroscopic moving bodies.
