It varies.

Explanation:

The refractive index differs depending on the medium. For example, the refractive index of a vacuum is 1. For water, it is 1.333. For diamond, it is 2.419.

The refractive index #n# of a substance can be solved with the formula #n=c/v#, where #c# is the velocity of light in a vacuum, and #v# is the velocity of light in the substance.
