Triple and quadruple rainbows have even been spotted. Even rarer, however, is the twinned rainbow, where two arcs split from a single base rainbow. "Everyone has seen rainbows, even double ...

which consists of two separate and concentric rainbow arcs, the elusive twinned rainbow appears as two rainbows arcs that split from a single base rainbow. Sometimes it is even observed in ...

They’re much more rare. When researchers, doing work sponsored by Disney, wanted to model one, they found that no one entirely understood the twinned rainbow phenomenon. They set to work with ...

From the researchers’ paper, the twinned rainbow appears on the far right. Photo: Wojciech Jarosz Who hasn’t been swept away by the stunning beauty of a double rainbow? Don’t get too ...

Researchers in San Diego say they've discovered how a rare "twinned rainbow" works and can now simulate one on a computer. By studying virtual rainbows, they figured out that the twinned rainbow ...

"We are the first to present an accurate simulation of twinned rainbows," Sadeghi said. The basic mechanism behind the formation of ... concentrated near the "rainbow angle" in the drop.

And what’s the science behind double rainbows? We have atmospheric optics to thank, as there are only two variables needed for rainbow formation: raindrops, and the sun. A raindrop acts like a ...

Mix two rain showers with different-size raindrops and the exotic twinned rainbow may come in to view. Each shower produces its own unique rainbow, which arcs along divergent paths, but the two ...

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 ...
