What does "impedance matching" actually look like? (electricity waves)
A 17-minute video by BetaPhoenix about electrical signals and circuits, on the Physics shelf. It came up in 2 Reddit threads, in r/Physics. It is pitched at intermediate level.

Makes impedance matching and wave reflections visible rather than presenting them only as formulas.
Study notes
Intermediate, Experiment. Step 3 of 6 in The physics under electronics
Helpful first
- Wave propagation
- Basic circuits
What it builds
- Watch a wave reflect from an open circuit.
- Infer an effective resistance from voltage and current.
- Connect impedance with a water model.
Useful moments
Check yourself: What changes when a transmission line is terminated by its characteristic impedance?
