<u>Dispersion is the phenomenon of the splitting of the light into its constituent colors when it passes through the prism.</u> White light is composed of seven colors which are Violet, Indigo, Blue, Green, Yellow, Orange, Red, written in the form of increasing wavelength. When the light passes through the prism it splits into these seven colors.
I do not think that I would because even though its a conductor in the insulator I think it would insulate it before it will work (not sure if that makes sense)
