Improvement suggestion for first prism figure.
This is a really great animation, and I can't say how happy I was to see it. One minor improvement- you should additively blend the the individual 'spectrum waves' to give an even tighter effect- the beam will start white because all of the overdraw as it enters the prism, and then the individual wavelengths will emerge in their true colour once they are sufficiently far out. The effect also suggests combination of these wavelengths causes white.

I have six reliable sources published by physicists and electrical engineers that are used as college textbooks that say the diagram, I put in the article is correct.
Griffiths, Introduction to Electrodynamics, third edition, 1999, fig 9.10 on page 379.
The various theories were very well-explained for the layman, I thought. Thanks to the author. 2601:346:1180:4320:858E:4187:D571:A1ED (talk) 15:59, 29 July 2022 (UTC)Reply[reply]
