Talk:Transparency (optics)
From Wikipedia, the free encyclopedia
What properties of materials makes them transparent? 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.
Article should also discuss Induced Transparency, Electromagnetically Induced Transparency and transparent metals (aluminium can be made transparent).
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.

[edit] 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?
