@@AndyMasley What about a standing wave coming from a high pressured natural gas pipeline that resonates with the walls and floors of structures such as buildings, houses, vehicles and human or animal body sounding line a diesel engine indoors with vibrations (beat frequency effect) heard in the walls and floors by 2% of the population in each area where it is occuring. The low frequency noise that never goes away causing eardrum pressure, earaches, headaches, insomnia, drowsiness, dizziness, disorientation, blurry vision, heart palpitations, hypertension called gas pipeline syndrome 24/7. Forcing people to leave their homes and all because of the phenomenon called The Hum. Can a gas pipeline cause The Hum?
After watching dozens of videos regarding standing waves (which were only based on formulas, graphs and mathematics ), finally I got a clear picture of standing waves in organ pipes in my head. So thank you Andy. The only doubt I am remained with is "is it possible to create a sound standing wave without organ pipe in the air just by blowing air with our mouth ? "
So the thing that's different about sound is that it's a traveling vibration through air particles, the air particles themselves aren't traveling, they just shake back and forth and impact the next air particle. It's the different between talking to someone across the room (very easy to send a vibration through the air particles) and blowing air across the room at someone with your mouth (the moving particles very quickly dissipate in the air before reaching the other person). Because blowing doesn't create the normal phenomena we associate with waves (maxima and minima, period and frequency) a standing wave (the result of two waves interacting) can't be produced.
5:33 How is it possible to have a node at an open surface? Wouldn't the particle from all the pressure simply push out at the surface, or is the tuning fork at the opening acting as a "barrier" because it is oscillating at the same frequency as the particles within the tube?
There are nodes along open points all along the rest of the waveform, as far as the air is concerned there isn't a difference between multiple nodes in a frequency and the open end of the tube.
@@JenkoRun I understand the logic of that statement but it intuitively it doesnt make any sense at all, what literal physical explanation is there for this? Nodes on a fixed point, like on a string makes sense, as it physically cannot move, but the literal opposite scenario serves the self same purpose?
@@MelloCello7 The air molecules don't travel when excited, they're the same as the rope or water that they perturbate without going anywhere, if you mean what stops the anti node of the open end of the tube from vanishing into the environment the pressure from the tuning fork acts as a closed end for the vibration, it influences the disturbance like a closed end.
Hi Andy, thanks for explaining. One question though: In the fork and water tube experiment, does the distance of the fork from the water have to be (wavelength of the fork's vibration in that air) x 1/2, 1, 1/5, 2 etc? Or will the nodes remain in the same spot if we keep the pipe the same yet pull away the fork further?
I see. So the aircraft has two types of vortex generator? The main? Engine, and the engine which propels the craft horizontally. In that case, how does it do a horizontal hyperjump?
The counter rotating magnets is for the vortex generation and the vortex will be focused on the dome of the aircraft producing a tube like wave patterns. I believe this is where you use the standing soundwave to amplify the vortex from inside the aircraft? So the sound wave could still work in vacuum of space? Is this true

Fantastic lecture! Thank you! I wish every professor would teach this subject this way
This is why cloning should exist, every ib school should be delivered a copy of you

So happy they've been helpful, thank you!
If all of his lectures are this lucid/intuitive, then I may have to immediately subscribe

This is one of the toughest topics to visualize and truly understand, yet you made everything seem so easy and simple and straightforward.

You could be a world class expansion chamber designer. 2 stroke pipe theory is what brings me here. Cheers!
You've done a great job with the animations. Thank You.
i literally thought i was never gonna understand this topic until you explained it thanks alot
Love the animations. Great visuals!
This is so clear thank you sm!
Brilliant !
Wow 😄, really helpful, keep it up

thankyou this is amazing
THANK YOU SO MUCH!!!!!!
Thank you so much 🙏🏻
thanks
I love you
Right back atchya
thank you so much!
Is this the reason Fit the 90 degrees Shift phase? When the pressure is maximum the particles aire full stopped so the velocity is 0
What happens if you increase the length of the tube?

sound waves cannot travel in space as there is no medium
But what about the horizontal hyperjump?
Best
im gonna cry i hate physics
I don't think peak waves can become trough wave, the software you are using might mislead some new wanting to learn about waves
Sorry what?
Thanks
