BBC新闻(双彩虹拍摄反映在奥克尼)(https://www.bbc.com/news/uk -苏格兰-北-东-奥克尼设得兰群岛- 50222151)显示了一种不寻常的双彩虹。根据这篇文章:>图像被马丁•格雷在Gyran周二早上,看到描述为“不可思议”。> >他说:“我习惯看到双彩虹,但这是一个很怪异的事情。”> >[...] > >"I quickly snapped a few photos. It was extremely bright, and odd looking - all odd angles. "But I didn't even notice the faint fourth arc until I carefully looked at my photographs." > >BBC weatherman Simon King said it was an "impressive" photograph. "It's a really impressive double reflected rainbow," he said. He said the photographer had a loch behind him at the time. > >As a result, sunlight had bounced off the loch before reaching the water droplets from a rain shower in front of him. The sunlight was then bent and reflected inside the droplet back to the photographer. **Question:** I've annotated the image and numbered each of the arcs. Is it possible to sort out what's going on and which phenomenon are responsible for each of them? ---- [](https://i.stack.imgur.com/BkbPy.jpg) Credit: Martin Gray & BBC; Gyran, Orkney Islands, Scotland
