Question

If medium 1 is vacuum then the refractive index of medium 2 is considered with respect to it is called ________​

Answer 1

Answer:

absolute refractive index

Explanation:

Answer 2

Answer:

Absolute Refractive

Explanation:

the refractive index of medium 1 with respect to medium 2 is denoted by n12. Absolute Refractive Index:When one medium is taken as vacuum and speed of light is taken in it, then the refractive index of second medium with respect to vacuum is called Absolute Refractive Index and it is generally denoted by n2.
