Solution

Absolute refractive index

When light is going from vacuum to another medium, then the value of refractive index is called the absolute refractive index.

Eg:light going from air to glass

Relative refractive index

When light is going from one medium (other than vacuum or air) to another medium, then the value of refractive index is called relative refractive index.

E.g.=light going from water to glass
