Feedback from Janneke Schenk
Friendly feedback from Janneke Schenk, auteur of the book "Over de Regenboog".
Over de Regenboog - Janneke Schenk
I found a compact and interesting book on rainbows, corona's, and other phenomena linked to our Sun. The book is written by Janneke Schenk and beside many and very beautiful pictures the book explains those phenomena's in an easy but still scientifically way.
Rainbows are impressive natural phenomena. But where do the colors of a rainbow come from? Why does it have the shape of a bow? Does a rainbow always look the same, and how big is a rainbow? Are all rainbow colors in the sky rainbows?
Janneke Schenk looked for answers to these questions and encountered other light and color phenomena on our way, such as the corona, glory, sacred and halos. She describes the physical explanation of these phenomena and makes them understandable for everyone with the aid of illustrations and photographs.
Through knowledge of the processes and circumstances you develop a feeling for where and when special light phenomena can be found in the sky and you will notice them more and more often!
