Optical Prism?

While shooting the spectacular morning of previous post, I noticed a bright patch of light to the right side of the island.

At first I thought it was a beam of sunlight breaking through the mist but as the morning brightened and at closer look, a spectrum of colour was clear.

The full range of colour became even clearer as it seemed to stretch and move closer to shore.

Physics was not a strong subject of mine in school and is still a challenge to process. Even searching on line to find what this is or how it is formed made my head hurt. The best (simplest) info I found was thisĀ Wikipedia article for ‘prism‘. What I do know is it was a treat to notice and capture it.
