Refractive Index Calculation Formula - GCSE Physics

The refractive index of a transparent material is a measure of how much it will refract a light ray.

The formula which links refractive index with the angle of incidence and angle of refraction is:

n = sin(i) / sin(r)

This is known as Snell's Law.

This tutorial includes a calculation of refractive index for the refraction situation.
