Tips and Tricks - Refractometer 1

The refractive index (n) is a physical property of a particular material. It is a dimensionless number that describes how light propagates through a specific medium.

The refractive index of a medium is a measure of how much the speed of light is reduced inside the medium related to the speed of light in vacuum.

The higher the medium’s optical density the lower the speed of light is inside the medium.
