Photons in TPT are modelled with physically correct dispersion in glass. Not only the Snell's law causes different wavelengths (colors) to refract at different angles, but photons with different wavelength move with different speeds in glass as well.

    TSspazz: It is really difficult to describe what's actually happening on the very primitive level. It involves quantum physics and whatnot. Light /actually/ has a constant speed, and at any time any photon travels at exactly that speed. The change in speed happens due to the photons... Uh, shall I say, being absorbed and re emitted again? I guess this is close enough. So any change in speed happens /in/ the medium.

    Why is this still on FP? This is from last year!

    Just a guess, but I think the actual changes in speed actually happen when the photons enter and exit the glass, not while they pass through it.

    I shortened the area between intermission and it made 3 different stripes of red, yellow, and blue

    If it sits long enough, it breaks into 8 individual strips of light, colors ranging from red to what is supposed to be violet.
