The thickness of the glass causes the white lights' components to bend and spread out its colors. The thicker the glass the more it bends. The red would be at the thickest and blue at the thinner part. Light actually slows down.
When light passes from one medium to another it is refracted, that is bent, the amount of bending depends on the wavelength. Different colours have different wavelengths and as white light is made up of all colours each is bent by a different amount, so the light is split
This is easy to do with a Prism, preferably a long triangular piece of glass. A glass of water can do the same thing, although not as accurate as a triangular shaped prism would.
A prism
A block of glass that can split white light into the many colors that it is comprised of is called a prism. The name comes from the traditional shape of the tool, which is a triangular prism.
Newton's prism was made of glass.
A prism. It can be made of glass, crystal, or other hard clear material.

Dispersion phenomenon is exhibited by the triangular prism. Dispersion is splitting of composite white light into its constituent colours.
A Triangular Prism
it happens when it is sunny and it then rains. try projecting white light through a glass triangular prism. Then all will be clear.

To show that light is made up of colours through diffraction.A prism is a 3d shape that is the same 2d shape all the way along. Many things are shaped as prisms. for example a glass triangular prism can be used to reflect or defract light in telescopes or to produce coloured light.
