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.
Refraction is the bending of light as it passes through one object to another. Vision occurs when light rays are bent (refracted) as they pass through the cornea and the lens. The light is then focused on the retina.The retina converts the light-rays into messages that are sent through the optic nerve to the brain.The brain interprets these messages into the images we see.ision occurs when light rays are bent (refracted) as they pass through the cornea and the lens.
