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.

Standing Waves can resonate in a pipe. The resonance occurs in an open-closed pipe when an odd integer number of quarter wavelengths fit exactly in the length of the cavity of the pipe. This animation illustrates what happens when a plunger is used to "scan" the effective length of a pipe driven by a tuning fork. Three different cases are shown for a set of increasing frequencies.
