Índice de Refracción

Definición

El índice de refracción (n) de un medio es la razón entre la velocidad de la luz en el vacío (c) y su velocidad en ese medio: n = c/v.

Explicación

Vacuum has n = 1 by definition; water is approximately 1.33, meaning light travels 33% slower in water than in vacuum. Diamond's high index of 2.42 causes the dramatic bending and internal reflection that gives cut diamonds their brilliance. Optical fiber uses the refractive index difference between core and cladding to confine light by total internal reflection.
