Answer:
Relative refractive index refers to the speed of the light when it changes medium. The rate of light's speed changes as it comes out of a medium and goes inside a medium. This change in the refractive index is known as the relative refractive index
Refractive index of a medium is the ratio of the speed of light in vacuum to the speed of light in the medium. Therefore, it has no units.
