Question

The ratio of speed of light in air to the speed of light in another medium is called as

Answer 1

Answer:

absolute refractive index

Answer 2

Answer:

the speed of light in another medium is called as Refractive index

Explanation:

Refractive Index (Index of Refraction) is a cost calculated from the ratio of the rate of mild in a vacuum to that during a 2nd medium of extra density. The refractive index variable is maximum usually symbolized through the letter n or n' in descriptive textual content and mathematical equations.Refractive index is a degree of the way mild propagates thru a material. The better the refractive index the slower the mild travels, which reasons a correspondingly improved extrade withinside the path of the mild withinside the material. Refractive index or the index of refraction is the ratio of the rate of mild in vacuum (or air) to the rate of mild in a obvious material.

The ratio of pace of mild in air to the rate of mild in every other medium is known as as Refractive index
