Refractive Index

The refractive index, or index of refraction of a material, is a dimensionless number that describes how light propagates through that medium.

The refractive index equals the speed of light in a vacuum divided by the speed of light in the medium.

Formula

$QuantityVariable["n", "RefractiveIndex"] == Quantity[1, "SpeedOfLight"]/QuantityVariable["v", "Speed"]$
