Answer:
No, the absolute refractive index of a medium can not be less than one because speed of light in any medium is always less than that in vacuum.
Explanation:
The absolute refractive index is defined as the ratio of the speed of light in vacuum and in the given medium. The absolute refractive index should never be less than 1.

Explanation:
No,
Absolute refractive index less than unity indicates that speed of light in that medium is more than that in a vacuum which is impossible. The absolute refractive index of a medium is the ratio of the speed of light in vacuum to the speed of light in that medium.
