The rainbow is a natural atmospheric phenomenon well-known to everybody. It is universally seen as a thing of beauty. However, there is much about the rainbow that is often missed.
We shall see a wide variety of rainbow phenomena some of which will be familiar to all of us, others will be not so well-known. We shall explain the double bow and why the colours are always in the same order. We’ll see rainbows in places other than in the sky and we shall answer the question “Can you see that rainbow?” All aspects can be explained using mathematics and physics met at school by the age of fourteen.
