Revision as of 06:48, 21 February 2006
This article is being vandalized a lot recently. Started about 4 days ago. Even the reversions still include vandalism now, because people are not looking carefully to which version it should be restored. Just for the record and for making reversion easier, the following link is to the last completely correct version at the moment:

Somebody put some wavelengths and/or frequencies in?ÇĢÇ+ɭ=92/3
This article covers very similar territory to Electromagnetic radiation. Shouldn't they be merged? -- The Anome
This article is very similiar in topic to that one ... JDR
What we really need here is a good (and colorful!) picture of the visible spectrum!!! Malbi 13:34, 2 Dec 2003 (UTC)
Removed statement about low wavelength EM being impossible to measure directly. There is no lower limit on wavelength detection, and one should be able to detect arbitrarily low wavelength EM via compton scattering.

Removed this from the UV section: "It was discovered to be useful for astronomy by a Mariner probe at Mercury, which detected UV that "had no right to be there". The dying probe was turned over to the UV team full time. The UV source turned out to be a star, but UV astronomy was born.". Even if it's true, it's badly written and no proof nor real data is given about it
Value of the speed of light corrected in km/s: from 300 (previous) to 300,000. Doctorcito 2 Aug 2005
Wouldn't it make more sense to have the colors in the wavelength/frequency chart near the bottom go from violet to red? Most electromagnetic charts go from high energy to low energy. Same with the page. D'Agosta 15:14, August 9, 2005 (UTC)
EM Spectrum "Timeline"
Has anyone made a "timeline" similar to this Vocal and instrumental pitch ranges chart? If not I think one should be started. Anyone want to help? Zhatt 19:51, August 9, 2005 (UTC)

Wave or/and matter-particle motion?
Hei.
I draw my opinion of this issue. You can read it on my web-page.

Basic ideas is.
Matter can behave different way.
1. Matter-particle can flow-motion without vibration. 2. Matter-particle can flow-motion with vibrate. 3. Vibrate cannot exist without matter-particles.
( Terms, vibrate means wave-motion. )
