The BBC News item Double reflected rainbow photographed in Orkney shows an unusual kind of double rainbow.
According to the article:
The image was captured by Martin Gray at Gyran on Tuesday morning, who described the sight as "amazing".
He said: "I'm used to seeing double rainbows, but this was a really weird-looking thing."
"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?
