Realistic Simulations Explain Physics of Rainbows
For being such an iconic and easy to understand phenomena, Rainbows have long been difficult to simulate mathematically. The recently meme’d double-rainbow has long been missing from most simulations, but thanks to some recent discoveries by researchers at UC San Diego, they may now be simulation reality.
Until now, most simulations of rainbows had assumed that water drops are spherical, which isn’t true for large rain drops, Laven says. In this paper, researchers have adopted a completely different approach and developed a more realistic model to recreate rainbows, he says.
“The simulations shown in this paper offer the prospect of a better understanding of real rainbows,” Laven says. “I hope that the next step will be to use these new techniques for a systematic investigation of rainbows caused by realistically shaped rain drops.”
