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.

Light
The article says "In physics, the term "light" may refer more broadly to electromagnetic radiation of any wavelength, whether visible or not"

Surely this isn't true. Nobody refers to radio waves or microwaves as light. BrianDGregory (talk) 15:14, 29 November 2023 (UTC)


 * I’ve a PhD in astrophysics. Plenty of folks I know refer to the EM spectrum generically as light, including radio and microwave. Hope that’s helpful! Alysaobertas (talk) 05:34, 5 January 2024 (UTC)
