Oh yeah, JB, I know it's all happening at such incredible speeds that it isn't distinct to us. It was just a theoretical question that helped me understand a little better.

What made me think about this was the very day I read this thread I saw a rainbow with three bands. Having now studied some about light, etc, I was pondering many things about the rainbow, especially that I was seeing three bands. Had me thinking about speed of light, light arriving from past times, etc. So revisiting the forum on that particular day and finding this discussion led me to ask the question.

Hi Gemma,

The study of the rainbow alone can make for endless hours of reading. The link below has lots of information and the links within this link can take you on for hours (if you're so inclined). :)

Thanks, JB, I will read it. Glanced over it and saw it has some familiar names (thanks to Doos' little gemology project for me ) :wink: so maybe it will answer some questions I have not even been able to phrase!
