refraktiokertoin
Refraktiokertoin, also known as the index of refraction, is a dimensionless number that describes how light or other electromagnetic radiation propagates through a medium. It is defined as the ratio of the speed of light in vacuum to the speed of light in that medium. The symbol commonly used for the index of refraction is 'n'.
A vacuum has an index of refraction of exactly 1. All other transparent materials have an index
The refractive index is responsible for the phenomenon of refraction, which is the bending of light as
