WebbDefinition. The relative refractive index of an optical medium 2 with respect to another reference medium 1 (n 21) is given by the ratio of speed of light in medium 1 to that in medium 2.This can be expressed as follows: =. If the reference medium 1 is vacuum, then the refractive index of medium 2 is considered with respect to vacuum.It is simply … Webbpyridinemethanol (2P) and glycerol were used as the high refractive-index diluent for silica beads (refractive index of ≈ 1.43 and ≈ 1.47 for different lots of beads used for this work) and PMMA (refractive index of 1.49). We demonstrate that 2P-water solutions work well at refractive indices up to 1.52 in these instrument counters.
