If you watched the previous episode you’re probably wondering how those weird loopy wavy things work (if you haven’t watch it yet click here). This episode explains it. The type of wave that is being created is called a standing wave and it occurs when two waves interfere with each other in just the right way.
Episode 9: Standing Waves part 2
If you want a little more detail about standing waves, The Physics Classroom has a nice explanation with some animations here.
Stay tuned for the next episode which will show you how to make a demo of this yourself and amaze all your friends!
