Stationary (Standing) Waves in Closed and Open Tubes | A-level Physics

We discuss longitudinal stationary sound waves in closed and open tubes (air columns). With the help of a simulation, we discuss their formation, key features, the formulae for frequencies of harmonics, and the differences between closed and open tubes.

Great animation! It really helps us understanding how the particles inside the tube oscillate and how could they produce nodes and antinodes. Thanks!

You're welcome :) All credit for the animation goes to Walter Fendt - check out the link in the description for more simulations by them.

Great explanation and great animation. I will be using this video with my students. Your doing a great job! Keep going!

[@ForestLearn]

Thanks for the encouragement :)

Good explaination, how can i make such animations for my students in urdu.
