\nThe refractive index of a material varies with the wavelength of light. For most transparent materials, including flint glass, the refractive index is higher for shorter wavelengths (like violet light) than for longer wavelengths (like red light). This phenomenon is known as dispersion.
\n<\/section>\n
\n– Shorter wavelengths are bent more than longer wavelengths when passing through a prism. This is why white light is dispersed into its constituent colours.
\n– Higher refractive index means light bends more, which corresponds to shorter wavelengths (violet end of the spectrum).
\n– Lower refractive index means light bends less, which corresponds to longer wavelengths (red end of the spectrum).
\n<\/section>\n
\nThe relationship between refractive index (n) and wavelength (\u03bb) is described by Cauchy’s equation, which states that for a given material, n is approximately proportional to A + B\/\u03bb\u00b2, where A and B are constants. As wavelength (\u03bb) increases, the refractive index (n) decreases. Violet light has a shorter wavelength than red light.
