Newton’s rainbow

The great scientist Sir Isaac Newton did not invent rainbows. But he did discover that white light consists on many colors, and can be split using a prism.

Most rainbows are shaped like a bridge in the sky, but this rainbow that I saw in Izu last month is the wrong way round.

I have no idea how this rainbow was formed (it was not raining at the time).

There was a huge typhoon which swept across Japan yesterday, and it left behind this beautiful rainbow, which was much lower and thicker than usual.

We don’t often get rainbows with green hills as a backdrop.
