The fundamental process at work in a rainbow is refraction -- the bending of light. Light bends -- or more accurately, changes directions -- when it travels from one medium to another. This happens because light travels at different speeds in different mediums.
The amount of bending depends on the change in lightâs speed as it passes from one material to another. The angle of change when light passes from air into a transparent material is called the refractive index of the material. We use the change in the angle of light whenever we wear corrective lenses.
