  1. I don't think the speed of light in a linear medium needs to be that complicated. The permittivity sets the coupling between free charge and the electric field, which determines the speed of propagation. Basically, the polarized medium screens charge (a la Lenz Law) and makes that coupling weaker, bam: the wave is slower.

  2. kinda ironic, since you need rain for a rainbow. You also need rain for....wait for it...a flood!

  3. time stamp?

  4. but why are sun dogs to the left and right, and not in a colored bow?

  5. probably out to 2000 nm, then there's a absorption peak. A 10 microns you'd just see your eyeballs.

  6. don't get hung up on semantics.

  7. which polarization? light polarization or polarization of a medium in an electric field (induced dipoles)?

  8.  @karlhendrikse  not really. Maxwell's eq in media with E -> D and B -> H via permeability and permittivity is super duper standard undergrad EM, more so than the phase-delay model. Personally, I prefer Jefimenko's Eqs which do away with "induction" entirely.

  9. no, it's the most understood thing in the history of science.

  10.  @corujariousa  ok. please name the light (or electromagnetic) phenomenon that is not understood:_______________________

  11. how?
