Aint a prism pyramid shaped?A prism can be pyramid shaped, but any piece of glass with surfaces that are not parallel will demonstrate the effect. Glass with bevelled edges is one example.The reason you don't see a rainbow spectrum with your double glazing is because the sheets of glass have parallel surfaces, so the bending effect gets cancelled out when the light emerges on the other side of the glass. At least, I think that's the reason.
When a beam of white sunlight enters a prism it is split up into a spectrum, a bit like a rainbow.Why does this happen?
