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.
Light travels in straight lines if the medium it travels through does not change. If light enters a new medium, it might slow down or speed up, because the speed of light is different for different mediums. If light enters the new medium perpendicular to the boundary, it will keep moving in the same direction. But if it hits the boundary at an angle, it will also bend. This bending of light waves due to a change in speed is known as refraction.
