It is a rainy day today here in Plymouth so it’s a good time for me to draw attention to a fascinating and very beautiful image of what visible light from the Sun looks like when it is split into its constituent colours in New Scientist Issue 2697 (28 February 2009). It would be a breach of copyright for me to include the image in this post but here is a direct link though to the image on its own.
