Question

What is the Refractive Index of a colored wire?

Answer 1

The ratio of the velocity of light in a vaccum to its in a specified medium is called a refractive index of a coloured wire.

Answer 2

Explanation:

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, n 1 sinθ 1 = n 2.
