Good. My friend, I think you should really SAY that the main purpose of the whole topic is modeling the PROPAGATION OF WAVE in a crystalline or periodic structure.
When you're explaining the reduced scheme, I was taught that instead of reflecting at each brillouin zone boundary, the wave coupld simply moved the reciprocal lattice vector in either direction. Since we also used a negative k-axis, I think this is slightly easier to understand than the reflection. Admittedly, our explanation for the movement was very mathsy, so probably not really suited to video.
So you need to build the brillouin zones out of the reciprocal lattice. How do you translate a crystal from real to reciprocal

What is wave with the different lambdas on Brillouin Zones ? what does it mean, wavelength, wave on the Brillouin Zones ?

Thanks anyway

Otherwise, great video, really well explained. Perhaps some relation to what they actually are, i.e. their relation to free electron theory.
