How are Rainbows formed?

Rainbows are formed because of the process of bending light knows as refraction. different colors of light bend at different angles when they refract. When light from the sun enters a droplet of rain, it refracts a tiny bit causing the colors of light to spread apart, the light then bounces, or reflects, off of the back of the droppled and refracts once again as it leave the dropplet on the same side it entered. By the time the light reaches your eyes the refraction is so noticeable that you see all the colors of sunlight spread apart - creating a Rainbow
