Review of Maxwell's Equations- Part II

This is a brief review of Maxwell's equations for an undergraduate course on lasers in an electrical engineering program at a large state university. The lecture covers much of the material in Verdeyen's book "Laser Electronics", chapter 1.

you say the wavelength will become longer when it enters the material, which is what I expected, but the diagram shows it becoming shorter?

[kridnix]

Oops, If I said longer, then I mis-spoke.  For :normal" materials the index of refraction, n > 1 so the wavelength is smaller in materials by a factor of 1/n.

Cool ! It's a good video ! More tech in "Wonderful electric energy-Tesla wireless" by HorizonDelta

nice but it's a shame the actual light matter interaction is skipped over because that's actual interesting part for maxwell. refraction was known long before maxwell but not the actual light atom concert. I would very much like to hear about how this freaky wave/particle rush manage to thoroughly interact with these very specific EM constellations yet come out unscathed as a whole. and what quality of the material decide if they do survive or get absorbed.

The units of Planck's constant is not Joules, but rather Joule-second.
