I saw a rainbow with several violet and green color bands inside??
These color bands are called the supernumerary bows and are a consequence of the wave-nature of light. The bands are caused by a phenomenon called light interference. Interference happens whenever waves of some sort in a medium interact with eachother. At some places, the waves amplify eachother, and at other places they extinguish eachother. Here, the waves are light waves, and the medium is air. The supernumeraries form when the raindrops are much of the same size. • I saw a rainbow that was straight (not round)?? You probably saw a small section of the rainbow, maybe with the sun low in the sky. If the rain-producing storm was in the distance, you’d have seen a short vertical pillar, which is just the base of the rainbow where it intersects Earth. • What are the spokes that can sometimes be seen in the rainbow? These are solar rays, seen from behind (solar rays are usually seen diverging from the sun). Since these rays are opposite the sun (where the rainbow is), they are called ant
