Electromagnetic spectrum[edit]

I've listed this article for peer review because this is a very topical subject for both physics and applications, in particular in the domain of radio frequencies. I am not sure is this would be best in an associated article Electronic spectrum/Radio spectrum. I am seeking contributions from users interested in the scientific content and the applications and economics.


Thanks,

Review by Jeff[edit]

We need to identify this article's purpose. I suppose this article needs to be an overview of each type of EM radiation. We have the article Electromagnetic radiation, but that actually does not really give an overview of the different types of radiation. I guess in an article like this I would expect to see each band (Radiowaves, Microwaves, Visible light etc.) have its own section, which would be a summary of each of the respective articles on the subject. Compare with Visible spectrum, and possibly use this as a model. Like most reviewers here at PR, I don't have the background to jump in and start writing constructively on a topic like this, but I can give some other suggestions to get you started.

  • I would avoid putting formulas in the lead section; these belong in the body, and use words to describe the concept in the lead.
  • "It is commonly said..." weasel words, don't use.
  • "that EM waves beyond these limits are uncommon, although this is not actually true." Confusing. If I say "don't think pink" what's the first thing you think of? State the facts as positive statements.
  • "The short wavelength limit is likely to be the Planck length" needs context to give it meaning.
  • "a atomic nucleus"
  • "Electromagnetic energy at a particular wavelength λ (in vacuum) has an associated frequency f and photon energy E." again, this statement needs context.
  • "When light waves (and other electromagnetic waves) enter a medium, their wavelength is reduced. " reword.

This needs more content before a review will be very useful but I do have a few thing:

  • If light=electromagnetic radiation make this clear in the first sentence. If not make sure the words are not used interchangably in the rest of the article.
  • Only have one chart of the spectrum. Hope not the horribly hard to read one that is the lead image.
  • Need citation style refernces.--BirgitteSB 17:11, 25 October 2007 (UTC)[reply]
