Questions this site addresses: what is a rainbow? where is the sun when you see a rainbow? what makes the bow? what makes the colors in the rainbow? what makes a double rainbow? why is the sky brighter inside a rainbow? what are supernumerary arcs? what does a rainbow look like through dark glasses? what are reflection rainbows?
