An optical prism is a transparent optical element with flat, polished surfaces that refract light. At least one surface must be angled — elements with two parallel surfaces are not prisms. The traditional geometrical shape of an optical prism is that of a triangular prism with a triangular base and rectangular sides, and in colloquial use "prism" usually refers to this type. Some types of optical prism are not in fact in the shape of geometric prisms. Prisms can be made from any material that is transparent to the wavelengths for which they are designed. Typical materials include glass, acrylic and fluorite.
A dispersive prism can be used to break white light up into its constituent spectral colors (the colors of the rainbow). Furthermore, prisms can be used to reflect light, or to split light into components with different polarizations.

I am looking for a mathematical derivation for the idea that symmetry of the light beam path through a prism gives rise to a minimum deviation.
Thanks.
can i use a prism to diffract(separate?) ultralight or microwaves,
if so, how far into the spectrum will it go?
for example, when i look at a rainbow, and the rainbow ends after the violet and before the red, does it really end? or am i just unable to see the missing wavelengths?

If you have two prisms on top of each other, one smaller than the other, and the one on top glids down to the ground the lower prisms moves to the left.
The problem is to find how far the lower prism moves.
How do you set up the Lagrangian and the constraints for this problem?
Any ideas?
