Question

Define refractive index, absolute refractive index, and relative refractive index.

Answer 1

Definitions:

1. Refractive Index: The refractive index is a measurement of how much a light ray bends when it passes from one medium to another.
2. Absolute Refractive Index: The refractive index is known as the absolute refractive index when light travels from a vacuum to another medium.
3. Relative Refractive Index: The refractive index is known as the relative refractive index when light travels from one medium to another.
