"Web17. jan 2011 · The refractive index (RI) of a polymer is the ratio of the speed of light in a vacuum to the speed of light through the polymer. It varies with frequency (and thus wavelength) of light. Typically, it is measured at well-defined spectral wavelengths; for example, the yellow sodium double emission at 589nm wavelength.
