Answer:
Refractive index has no units because the refractive index is the ***ratio*** of the speed of light within the material of interest divided by the speed of light in a vacuum, thus the consistent units of measure (meters per second, or kilometers per second, etc.) cancel out and you’re left with just a number know as the index of refraction.

Answer:
Refractive index is a property of any material, which describes how fast the light travels through that material. It is the ratio of speed of light in vacuum to the speed in light in that material.
Since it is the ratio of same physical quantity. It doesn't have any unit.
