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.
This is because light follows the inverse-square law. For example, a point source like a candle that causes an illuminance of 1 lux on an object one meter away would cause an illumination of 1/4 lux on the same object two meters away, or 1/9 lux on the object when it is 3 meters away. Being precise about metrics for lighting and daylighting is important.
