Wavelength and optical spectrum

Hi, i think the label of the x-axis ("wavelength") and the representation of the optical spectrum are wrong. x-axis looks like it is in wavenumbers (unit cm-1) as typical rotation-absorption peaks appear around 1540 and 3200 cm-1. There for the optical spectrum (rainbow) can not be below 1000 whatever units in the sprectrum as it would be 1000 cm-1 and lower. This is mid and far infrared region not the visual optical spectrum (below 1000 nm). the visual spectrum above 10.000 cm-1 and therefore not shown in your data. Please fix the graphics. Thanks --Cepheiden (talk) 09:09, 7 August 2021 (UTC)

Reviewing this file, I believe you are correct. It appears that the spectrum is still with wavenumber (cm-1) rather than wavelength (nanometers), and the visual spectrum is in the incorrect place on the figure. There is a much better, and correctly label figure, but similar graphic available here: File:Synthetic_atmosphere_absorption_spectrum.gif. I'll send a request to have this figure deleted. Thank you for bringing this to my attention. — Preceding unsigned comment added by Benjamin J. Burger (talk • contribs) 16:09, 9 August 2021 (UTC)
