X-ray Diffraction, Bragg, Laue, Reciprocal lattice, Fourier, Plane waves, Brillouin zone

This lecture should be the first to be viewed out of the four I have uploaded. you may check the other ones:
structure/form factors and cubic systems
Powder diffraction and Ewald sphere (2 videos)
X-ray Diffraction, Reciprocal lattice, relation to plane waves and Fourier, Brillouin zone
Note: There are sound-track problems. Sorry. This happens randomly it seems when Powerpoint builds the video (in a slow PC). Hopefully, the written text would be self-explanatory.
sound of slide 13 is the same as in slide 8.
sound of slide 35 is the same as in slide 7.

This is excellent teaching. Thank you, from one physicist to another.

Thank you very much! It is good to hear positive feedback from students, but it is also very nice to get such positive comment from a peer, and it is quite rare!

Awesome video for anyone taking solid state physics. Thank you so much for the help.

great lecture, using to study for my qualifying exam. Thanks!

Great stuff!

very clear and funny 😂

Sir, your voice_audio is missing somwhere in the video. Please correct it.

[@bgelloz]

Thanks for your input. I had identified 2 problems with audio, as described in the video description. Slides 13 and 35. Audio in KZbin cannot be altered after publication. Maybe captions could be added. I will see when I have time. If it only for slides 13 and 35, as written in description, the written text should be self-explanatory. I f you refer to another problem, please let me know. Thanks.
