Talk:Infrared window

From Wikipedia, the free encyclopedia

[edit] Underestimate?

"...can stay in the atmosphere for over fifty thousand years, a figure which may be an underestimate given the absence of natural sources of these gases."

Does it follow that a lack of natural sources could lead to an underestimate of the duration? Leonard G. 04:28, 23 Mar 2005 (UTC)

[edit] Too narrow a definition

The atmospheric window goes to much longer wavelengths than infrared. Radio and radar waves below Ku-band frequencies, and also Ka band (around 35 GHz) and W band (around 94 GHz) are also widely used atmospheric windows. -Amatulic 00:04, 2 March 2007 (UTC)

I believe that's covered in the Radio window article! (Or is it the Astronomical window or Optical window article?) Ewlyahoocom 17:18, 2 March 2007 (UTC)
You're right, thanks. This article could use a paragraph describing the other atmospheric windows, rather than a list of "see also" links. In my line of work, "atmospheric window" and "radio window" are interchangeable terms. -Amatulic 18:06, 2 March 2007 (UTC)
Should they be merged? Ewlyahoocom 17:29, 3 March 2007 (UTC)
I think so Sagittarian Milky Way 03:50, 13 June 2007 (UTC)

"The atmospheric window refers to those parts of the electromagnetic spectrum that are, with the earth's atmosphere in its natural state, not absorbed at all. The atmospheric window lies approximately at wavelengths of infrared radiation between 8 and 14 micrometres." The first sentence and the name of the article are general, covering visible, IR and RF, but the second sentence and the body of the article are specifically IR. Seems to me, either the first sentence and the name of the article should be changed, or the second sentence and the rest of the article. I'm inclined to think the article is a nice one about the IR window, and we don't need a general article, so the name should change, but perhaps some will come to the opposite conclusion.
