The ratio of speed of light in a given pair of media , gives us a measure of the extent of refraction of a ray of light as it goes from one medium to another. We use this ratio to define a term called the relative refractive index for a given pair of media . A relative refractive index is light that passes from one transparent medium to another.

What is the dimensional formula for relative refractive index is?
The dimensional formula for relative refractive index is [M^0 L^0 T^0].
Can relative refractive index between two media be less than unity?
No, the relative refractive index between two media cannot be less than unity. The relative refractive index is defined as the ratio of the speed of light in a vacuum to the speed of light in the medium, and since the speed of light is always slower in a medium than in a vacuum, the relative refractive index is always greater than or equal to 1.
What does relative refractive index tells?
The relative refractive index describes the change in speed of light as it moves from one medium to another, indicating how much the light bends or refracts at the interface of the two media. It is calculated as the ratio of the speed of light in a vacuum to the speed of light in the medium in question. The larger the relative refractive index, the more the light is bent or refracted as it enters the medium.
What is the value of absolute or relative refractive index?
The absolute refractive index is a measure of the speed of light in a medium compared to its speed in a vacuum, while the relative refractive index compares the speed of light between two different media. Both values help determine how light is bent or refracted as it passes through different materials.
What is refractive index?
The refractive index or index of refraction of a substance is a measure of the speed of light in that substance. It is expressed as a ratio of the speed of light in vacuum relative to that in the considered medium.A simple, mathematical description of refractive index is as follows:n = velocity of light in a vacuum / velocity of light in mediumHence, the refractive index of water is 1.33, meaning that light travels 1.33 times as fast in a vacuum as it does in water.

Differences between relative refractive index and absoulate refractive index?
Refractive Index(i) Refractive index of a medium is that characteristic which decides speed of light in it.(ii) It is a scalar, unit less and dimensionless quantity.(iii) Absolute refractive index :When light travels from vacuum to any transparent medium then refractive index of medium w.r.t. vacuum is called it's absolute refractive index i.e. vacuumµmedium = c/vAbsolute refractive indices for glass, water and diamond are respectively µg = 3/2 = 1.5, µw = 4/3 = 1.33 and µD = 12/5 = 2.4(iv) Relative refractive index :When light travels from medium (1) to medium (2) then refractive index of medium (2) w.r.t. medium (1) is called it's relative refractive index i.e. 1µ2 = µ2/µ1 = v1/v2 (where v1 and v2 are the speed of light in medium 1 and 2 respectively).(v) When we say refractive index we mean absolute refractive index.(vi) The minimum value of absolute refractive index is 1. For air it is very near to 1. ( 1.003)
What is the relationship between viscosity and refractive index?
There is no direct relationship between viscosity and refractive index. Viscosity relates to the resistance of a fluid to flow, while refractive index is a measure of how much light bends as it passes through a substance. However, the refractive index of a substance may change with temperature, which can in turn affect its viscosity.
