- I'm a little worried about the diagram being misleading since it depicts the speed of light as being larger for lower frequencies. Isn't that inaccurate? hinnk (talk) 02:57, 28 September 2024 (UTC)
- It isn't misleading. It's accurate. The fact that higher frequencies travel through more cycles, in a given time span, does not mean (or imply) that they move slower. In air all frequencies are moving at the same speed. In the prism the higher frequencies are moving slightly slower, as they should (in this case 25% slower). Also the relations between frequencies, speeds and angles of deflection are proper. Bammesk (talk) 15:02, 28 September 2024 (UTC)
- Cool, I'll take your word for it. This was an issue in a previous version of the image (see c:File talk:Light dispersion conceptual waves.gif) so I'm glad it's been fully corrected in the current one. hinnk (talk) 23:23, 28 September 2024 (UTC)
