What is absolute refractive index?

Absolute refractive index of a medium is the constant of ratio of sin i to Sin r of the medium where i is angle of incidence in air or vacuum and r is angle of refraction in the medium.

Or

This is the ratio of the speed of light in a vacuum to speed of light in a medium.

 

Thus refractive index, n = (speed of light in a vacuum, c)/ (speed of light in a medium cm )

    Isn’t absolute refractive index different from mere refractive index?
