There are different types of light on the spectrum as many of you science geeks will know. These are made up of different frequencies and wavelengths. My question is this:
Is there an ACTUAL light on the spectrum that can be visible, cut things and reflect its self just as a lightsaber does and if so what light is it?
I don't care if the answer is canon or not. I'm just wondering if this has ever been explained throughout the Star Wars universe.
I am not looking for a lightsaber tutorial, unless that explains what wave length the light is.
