The scientists recreated a wide variety of rainbows -- primary rainbows, secondary rainbows, redbows that form at sunset and cloudbows that form on foggy days -- by using an improved method for simulating how light interacts with water drops of various shapes and sizes. Their new approach even yielded realistic simulations of difficult-to-replicate "twinned" rainbows that split their primary bow in two. |
