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)[reply]

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)[reply]

That is an American English pleonasm of fairly recent origin. It only complicates things and should be avoided. Light is visible electromagnetic radiation. We define what's bright, dark, blue or orange by our average senses. There really is no need for complicating things by stomping on very old definitions that work just fine. Lajoswinkler (talk) 21:31, 16 November 2024 (UTC)[reply]

We paraphrase reliable sources. Yes, the entire spectrum is light. Constant314 (talk) 22:08, 16 November 2024 (UTC)[reply]
