how does the index of refraction of an unknown substance compare to the index of refraction of a vacuum? explain how the speed and the refraction of light would behave in both?

Answer:

By measuring the speed of light in both in space and that unknown substance

Explanation:

Refractive Index (Index of Refraction) is a value calculated from the ratio of the speed of light in a vacuum to that in a second medium of greater density.

By measuring the speed of light in that medium and dividing it by speed of light 3*10^8 we can measure the refractive index of any medium
