(updated version) Longitudinal Standing Waves Demonstration

Standing longitudinal waves are demonstrated and compared to an animation to help with understanding what the heck is going on. Want Lecture Notes? This is an AP Physics 1 Topic.

Thanks to Dan Russell for pointing out that I was not clear enough with density vs. displacement nodes and antinodes. The last minute of the video clears that up. You will find more about this at his website:
