Refraction happens when a wave changes speed at a boundary.

- A change in its medium.

The absolute refractive index of a material, n, is the ratio between the speed of light in a vacuum, c, and the speed of light in that material, v

n = c / v

Converging Lenses change the curvature of wavefronts
