A twinned primary rainbow produced through computer simulation. The rainbow is split because of the interaction of light with two types of water drops: some smaller, spherical ones, and some ...

Don’t get too excited, though, apparently there’s an even more rare and “exotic” phenomenon called the twinned rainbow, in which two rainbows appear to split from a single stem.

Researchers in San Diego say they've discovered how a rare "twinned rainbow" works and can now simulate one on a computer. IE 11 is not supported.

But today, funding for rainbow research is scarce and so is work on the topic. Jensen's quest to learn about the physics of rainbows led him to the Light and Color in Nature conference at St. Mary ...

The middle of a rainbow’s circle lies directly opposite the sun. At dawn, this central point is on the horizon—exactly half of the circle is visible and the rainbow rides high in the sky.

The key to the twinned rainbow mystery, Jarosz said, is the combination of different sizes of water drops falling from the sky. "Previous simulations have assumed that raindrops are spherical.
