Wikipedia:Picture peer review/Light Dispersion

Light dispersion conceptual waves


A very similar picture was nominated about a year ago (but was not promoted), however I think this one is better by far. It accurately displays the dispersion of light through a prism, and is quite well-made and an interesting picture to look at. I'm just not sure if I should put it up on the "real" picture nomination on WP:FPC.

 * I do like the wavelength changes with frequency, but do wonder if they are in the correct proportion (it looks fairly close, visible light ranges from about 400-700nm). I don't like the white light being divided into seven colours or the scale of the prism relative to the wavelength, they are likely to mislead the viewer. The continuous waves might also mislead the reader as to the true nature of light. Frankly I find File:Dispersion prism.jpg or File:PrismAndLight.jpg superior since they keep it simple rather than introduce lots of technical inaccuracies. The idea of showing wavelengths might be useful in illustrating Snell's law or something similar. I don't think it'd succeed at FPC because of all the possible enc problems.
