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.

Sound Wave Interference (MIT Demo)

Two speakers, mounted on the table and facing each other, are driven by a function generator. A microphone is introduced between the speakers and the sound waves are displayed on an oscilloscope. This demonstrates the effect of interference and the resulting phase shift on sound waves over a fixed distance. Three different frequencies are demonstrated; 880Hz (A5), 440Hz (A4) and 523.3Hz (C4).
