9:10 is awesome. I've looked all over TH-cam and the internet for a good explanation of how wind instruments work. This is the first good explanation I've found! Awesome work dude.
How do you never look a day older, even after all these years!, Just wanted to say thanks for helping me with undergraduate physics and applied physics. I'm now in med school but watch all your videos regardless, thanks again!
Perfect timing Mr. P! I am teaching this right now to my I.B. physics class and your videos are a great tool and inspiration! Thank you for all you do.
Thank you for talking about the differences between displacement and pressure nodes/anti-nodes! That was a detail that was glossed over in my AP class...We also never fully visualized the waves as being longitudinal lol
Hello, Thanks for your explanation. May be you could shed some light on what happens on a side flute(traverse flute) which is some kind of mix between open hole on both sides but at the same time has to the left of the embouchure blow hole a cavity which ends in a closed end, and I believe this volume of air acts in a way as a compressor ,resonator. Would you know how this system works or a place where I could dig deeper into the matter. Thanks in advance. Alex G
I forgot to ask if what happens to the air molecules being compressed and released, if they can be visualised in any way or diagram? The behaviour inside the tube is easier to picture, but what happens in that resonator towards the closed end to the left of the blow hole isn't easy to picture. If there's a votex or a suction system of any sort taking place. Hope I managed to explain myself to be understood. Thanks for your time and interest. Alex G.
Please watch these two videos about standing waves. I think it will help your understanding. www.flippingphysics.com/standing-waves.html and www.flippingphysics.com/standing-wave-longitudinal.html
The original video is of an object rotating on a turntable. I then motion tracked the object in Motion and isolated just the horizontal motion and applied that to a single dot to get a dot moving in simple harmonic motion. Then I imported that in to Final Cut Pro and made many, many, many duplicates of it in various configurations. So many duplicates it actually crashed my computer and I had to export groups of dots in a series of videos and then reimport those back in to Final Cut Pro to make it work. Hope that helps!
I never had this kind of knowlege in my country I freaking love this explanations!!! I was wondering... How do you know if in an open end the wave isnt out of fase? I mean is it always going to be an antinode? Why is that... Or maybe it could be a little bit to the right or left.... Making it not perfect... I dont know if what I just write its ok sorry for my mistakes I dont have good english XD thanks! For the videos!!
You have to be really careful here. Do you mean a displacement or pressure antinode? I actually answer all of these questions in the video. I would suggest watching the video starting at 7:21. Thanks for the compliments!
but wait, this ignores the inversion factor of the pipe. The diameter of the pipe affects it's resonant frequency, not just the length. What's the the real formula? This seems like an over simplification of what is really happening, which is inversion of the waveform before every antinode...

one of the best educational TH-cam videos I've seen in the last decade
High praise. Thank you!

I am a physics teacher and your videos are great...THANKS..your way of explaining matches perfectly with mine, so great..thanks for your work
You are very welcome. Glad to help your students learn!

This is awesome!
(Best of luck in med school. Remember to sleep.)
Perfect timing Mr. P! I am teaching this right now to my I.B. physics class and your videos are a great tool and inspiration! Thank you for all you do.
You are welcome! I hope you're I.B. class enjoys learning about the physics of musical instruments.
Thank you for talking about the differences between displacement and pressure nodes/anti-nodes! That was a detail that was glossed over in my AP class...We also never fully visualized the waves as being longitudinal lol
Glad to help. Visualizing longitudinal waves is difficult, however, very necessary.
you are a boon for the physics fraternity
Dude, you are amazing
Man, you are amazing❤🎉

lol my teacher went over standing waves in pipes in four minutes. What's the point of school when I can learn online from people like you
What is the mean Pressure inside the organ pipe in terms of atmospheric pressure?
thanks a lot! these are really good :)
You are welcome!

Thanks
Thanks for the donation!
nice vid
thanks
why does air particle not oscillate at nodes?
Please watch these two videos about standing waves. I think it will help your understanding. www.flippingphysics.com/standing-waves.html and www.flippingphysics.com/standing-wave-longitudinal.html
thank youuu
Can you do an explanation on resonance?
I already did. www.flippingphysics.com/resonance.html
Does anyone know which program he uses to create these animated videos?

Great video, Please just get yourself a lavalier mic
