Hi, Explain this:
Prisms split up "white" light into its component parts. but when coloured light passes through glass, it is also affected in different ways. A simple proof... Write "carbon dioxide" on a piece of paper, the first word in red and the second in blue. These colours represent reasonable extremes of the visible light spectrum. Now hold a wine glass stem horizontally over the words. Looking through the stem at the words, you will see that the word in red has been inverted whilst the word in blue has not. QED. Or is it? I'm off for the weekend. I'm sure that, by Monday, someone will have come up with the answer..... mike - This message is from the Pentax-Discuss Mail List.
