Welcome


The title says it all: this blog features physics videos found everywhere on the web: animations, demonstrations, lectures, documentaries.
Please go here if you want to suggest other nice physics videos, and here if I mistakingly infringed your copyrights. If you understand French, you'll find a huge selection of physics videos in French in my other blog Vidéos de Physique.

Reflection from an impedance discontinuity

Two segments of the Bell Labs apparatus are connected. The segments have different impedance. When a pulse travels from high impedance to low impedance, it is reflected with positive polarity and transmitted with positive polarity. When a pulse travels from low impedance to high impedance, it is reflected with negative polarity and transmitted with positive polarity.
