That is not the right spectrum for the sun. [[Special:Contributions/108.162.219.193|108.162.219.193]] 20:44, 27 December 2013 (UTC) | That is not the right spectrum for the sun. [[Special:Contributions/108.162.219.193|108.162.219.193]] 20:44, 27 December 2013 (UTC) | ||

:The picture of Guru-45 a few lines above is great and explaining the situation very well. It should be included in the explain. --[[User:Dgbrt|Dgbrt]] ([[User talk:Dgbrt|talk]]) 16:04, 27 December 2013 (UTC) | :The picture of Guru-45 a few lines above is great and explaining the situation very well.

− | + | I agree that the color band representing the spectrum of visible light given is not directly related to the (human) visible | |

− | + | "an angel, but still usually lit" ... aren't angels glowing in general? Did you ever see an angel who wasn't glowing? :-) -- [[User:Hkmaly|Hkmaly]] ([[User talk:Hkmaly|talk]]) 10:55, 27 December 2013 (UTC) | |
