Answer 1

Answer:

The refractive index determines how much the path of light is bent, or refracted, when entering a material. This is described by Snell's law of refraction, n1 sinθ1 = n2 sinθ2, where θ1 and θ2 are the angles of incidence and refraction, respectively, of a ray crossing the interface between two media with refractive indices n1 and n2. The refractive indices also determine the amount of light that is reflected when reaching the interface, as well as the critical angle for total internal reflection, their intensity (Fresnel's equations) and Brewster's angle.

Answer 2

Answer:

the ratio of the velocity of light in a vacuum to its velocity in a specified medium.

Explanation:

Formula

n = c

____

   v

n = refractive index

{c} = speed of light

{v} = phase velocity of light
