Question

What properties of materials makes them transparent? — Preceding unsigned comment added by 82.33.131.54 (talk) 10:47, January 16, 2005 (UTC)

That depends on the structure of the electrons of the outer shells of the substance and in particular, how these electrons interact in the solid body being the material. There is a complicated theory "predicting" (calculating) absorption and its spectral dependence of different materials.— Preceding unsigned comment added by 145.64.134.241 (talk) 11:03, September 7, 2005 (UTC)

Induced transparency

Article should also discuss Induced Transparency, Electromagnetically Induced Transparency and transparent metals (aluminium can be made transparent). — Preceding unsigned comment added by Vinsci (talk • contribs) 18:36, March 17, 2005 (UTC)

Difference between transparency and translucency

May I sugest the following difference between TRANSPARENT an TRANSLUCENT: 

  A transparent body lets more or less light go through, BUT does not affect the
  information transmitted (imagine for example the dark glasses used to observe a
  solar eclipse).

  A translucent body, on the other hand, prevents the information to get through:
  there is light going through, but one can not distinguish what is on the other
  side.

Induced Transparency, Electromagnetically Induced Transparency and transparent metals (aluminium can be made transparent). Are on the AMB page under Engineering. Mion 15:20, 22 January 2006 (UTC)

Still needs

I'd like to see more of a discussion of this. That is, what are the physics of transparency; what's happening with light waves/photons that allows them to pass through a transparent material. A brief discussion of other EM wavelengths would be nice too; i.e., noting how (for example) brick walls are transparent to longer radio waves, though not to microwaves.

Solids

What is the most transparent solid? Plexiglass lets more light through than glass, but it's still possible to see light reflecting off of it. Is there a solid that lets so much light through that it's almost impossible to tell that it's there?

general quality of discussion low

This page doesn't have a very cogent discussion of the physical processes (scattering and absorption) involved in making a material "transparent", "translucent", or "opaque"...52.128.30.23 20:09, 25 May 2007 (UTC)Jim

Pyrex not a plastic?

The phrase, "most glasses, and plastics such as Perspex and Pyrex" implies that both Pespex and Pyrex are plastic. Pyrex isn't a plastic. 140.147.160.34 (talk) 22:21, 2 January 2008 (UTC)Stephen Kosciesza
