EM to Optics 15 : Magnetic Field Perpendicular to Propagation Vector
Channel: Adam Beatty
Date: 2013-08-11

In this video I continue with my tutorials on Electromagnetism to Optics which is pitched at university undergraduate level. I have intended for a long time to record videos which describe the transition made from classical electromagnetism to optics. In many respects these videos will cover 'wave' optics. I devote much time to discussing the complex exponential representation of waves, Maxwell's Equations, the wave equation etc.   I would like to apologise for my hand writing - I have just bought a new tablet and am getting used to writing with it. I can assure you that it is better for later videos!

Specifically here, I derive the result that in free space - the magnetic field and the propagation vector are perpendicular. This is an extremely important result. Later we see that the electric field (in free space) is also perpendicular to the propagation vector and the magnetic field.

I hope it's of use!! Thank you for watching and I hope that this matches your requirements. Please feel free to provide feedback via comments and share with your friends.
