•  Neutral the radio looks a bit like a camera to me :/ Rama 14:44, 10 January 2006 (UTC)

<smile>like a camera?</smile> i do not see that? Tatoute 15:57, 10 January 2006 (UTC)

Well, a stylised older radio like this sort of looks a little bit like a modern compact digital camera... At least, that's what I first read at a first glance, I went "why is the visual domain so far right ?"; then I though "this is the definitely the domain of radio waves..."; and then I understood that this was actually a radio. Oh well, maybe I am weird :p Rama 12:51, 11 January 2006 (UTC)

ohh... Maybe i the antenna is not very visible at the scale of the thumbs ... but in full page it seems ok? You do not think so? Nevertheless thanks for your comment, nothing weird in it ;-) Tatoute 21:24, 11 January 2006 (UTC)

Things which are more typically "radio-like" would be

• antenna
• knob on the side
• a grid on the loudspeaker

but frankly, it is quite all right :) Rama 13:54, 20 January 2006 (UTC)

Excellent suggestion (the knob on the side is present but too small i think)

I modified the picture (grid on the speaker, bigger knob), is the new version better? Tatoute 11:55, 21 January 2006 (UTC)

I see where Rama was going with this :), if you take out the antenna, it looks like one of the many new canon pocket camera models, but you pros probably never heard of anything other than SLRs :) --Spundun 05:11, 20 January 2006 (UTC)

Since this is a "featured image" I might just raise the question here before starting to edit. The wavelength range given for infrared/heat radiation is 1 mm - 1 cm. However, the infrared range begins just outside the visible spectrum, i.e. at c:a 1 цm (micrometer) - a thousand times shorter, says Storebror 20:22, 2 February 2007 (UTC)

(undent) Yes it is simply wrong, unless one grants artistic license and considers the infrared band combined with the visual band. The 1 mm to 1 cm range is still wrong for microwaves, but less so. A suggested fix is to make the visual and microwave bands slimmer, and then insert an infrared band between them. I have done something similar with a derivative. Here is a suggested request to the Commons:Graphic Lab School/Images to improve department. I have not made the request yet in case anyone has different ideas and because I may ask User:Tatoute first.

• 
  Electromagnetic spectrum illustration to be fixed by inserting an infrared band
• 
  diagram showing where the infrared band should appear and the correct wavelengths to use

Article(s): almost everywhere; and see w:en:Electromagnetic spectrum for background needed to understand problem

Request: Please squeeze in an infra-red band icon between the rainbow icon and the microwave icon. Please also correct the wavelengths as shown in File:Spectre Terahertz.svg, or refer to w:en:Electromagnetic spectrum. I can do a stop-gap fix myself by copy and paste from the second image but I doubt the result will be the high quality a featured picture deserves (I had problems with the font, and my quickfix icons do not look good in closeup). -- 84user (talk) 02:08, 28 May 2009 (UTC)

Update I have finally got around to posting the above request at Commons:Graphic Lab School/Images to improve#Spectre fixes. 84user (talk) 17:27, 1 August 2009 (UTC)

0.01 nm = 10 pm

If we use 1 cm instead of 0.01 m, 1 mm instead of 0.1 cm, 1 nm instead of 0.001 μm, I suggest usind 10 pm instead of 0.01 nm.

Ohh, where are the μm waves?

Infrared

This image is wrong. Infrared light is electromagnetic radiation with a wavelength between 0.7 micrometres and 1 mm. β₁₆ - (talk) 10:56, 18 August 2010 (UTC)
