Definitions:

Refractive Index

Refractive index is a measure of how much a material slows down light as it passes through it. It is defined as the ratio of the speed of light in a vacuum to the speed of light in the material.

The refractive index is denoted by the symbol "n", and it is a unitless quantity.
The refractive index is a fundamental property of a material, and it depends on the chemical composition and physical structure of the material.

Absolute Refractive Index

The absolute refractive index, also known as the refractive index, is a measure of the degree to which a material can bend light. It is the ratio of the speed of light in a vacuum to the speed of light in the material. It is a fundamental property of the material, and it depends on the chemical composition and physical structure of the material.

Relative Refractive Index

The relative refractive index is a measure of the difference in refractive index between two materials.

It is the ratio of the absolute refractive index of one material to the absolute refractive index of another material.
The relative refractive index is used to compare the refractive properties of different materials, and it is often used in optics and materials science.
