How does a prism turn colored light into white light?
White light is not a single wavelength. Our eyes perceive three major colors, and fabricate "white" from that. The speed of light in materials is a function of wavelength, and so the different wavelengths of light are bent slightly differently upon entering the material of the prism, and bent again slightly differently upon exiting. The net is the violet light is spread one way, and the red a different way, with the other colors arranged in between. So Lets Say: --------------------------- <= Ultra Violet Light>>>|Prism| |Spectrum| --------------------------- <= Infared U & I are the to rays coming out of the prism from the white light

How do you make a rainbow inside?
White light passing through a prism will defract into the component wavelengths from infra red to ultra violet.
