Inside vs outside rainbows… I don’t mean indoors vs outdoors… but have a look at the following picture:
I have noticed that rainbows seem to be lighter on the inside of the bow, and darker on the outside. Is that simply an illusion or is there something more sinister taking place?
that works if you go view image, it might fix itself
refractive index?
I think I see what you’re saying now
Look up Alexander’s band.

That’s the sort of thing I’m trying to explain :) Cheers!
From that link: “The minimum deviation angle for the primary bow is 137.5°. Light can be deviated up to 180°, causing it to be reflected right back to the observer. Light which is deviated at intermediate angles brightens the inside of the rainbow.”
Well that has a simply identified answer to it, thanks :)
Then there was this
in this book
. This book is trash.
