AT&T Tech Channel · Apr 3, 2012 · 28m 3s
What this video covers
A Bell Labs film in which Dr. J.N. Shive uses a mechanical wave machine to demonstrate reflection, standing waves, resonance and impedance matching. He includes some equations but relies mostly on real-world examples a layperson can follow.
Why it surfaced in Hacker News
HN repeatedly calls it the clearest introduction to waves and transmission-line behavior, better than modern explainers.

Recommendation context
Short excerpts from positive mentions. Open the source to read the full Hacker News discussion.
“I didn't really understand waves until I saw”
“made standing wave, reflections, energy loss due to impedance mismatch, and impedance matching much clearer than anything else I've seen”
“By far the best introduction to the subject of waves of any sort.”
