Amelia AdamsThe unit for the index of refraction is dimensionless, as it is a ratio of the speed of light in a vacuum to the speed of light in the medium. It does not have any specific units.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
