EM to Optics 5 : Complex Numbers for Optics
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 complex representation of the trigonometric functions Cos and Sin which allows us to transfer to using complex exponentials for our study of both electromagnetism and optics.

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.
