Refractive index and refraction angle in a glass are dependent on the wavelength. Hence a glass prism can be used to disperse (decompose) light into different wavelengths (colours). In this digital composite red,green and blue overlapping laser beams are incident on a glass prism. Together,they are perceived by the eye as a single white beam (top left). After refraction in the prism the three colours are spatially separated | |
