just for anyone wondering, N stands for node, A stands for antinode. Nodes mean the points on the strings that appears to stand still, and antinodes are the points on the string that are oscillating with 'maximum amplitude'. + some people have pointed out that the antinodes are points that oscilates with 'maximum amplitude'.You're right.

I know this was intended as a physics demonstration, but it also works remarkably well for music theory in terms of subdividing a beat. I was half expecting the layers to overlap to show different rhythmic syncopation.
@@instakillgaming probably a drummer- at least a musician. I would have been impressed if he went higher, but that might not have been possible with that rope. 3,5,7, couplet syncopation is done by all *actual* musicians… but not typically with a rope.
This brings back memories. I did basic training in 97, and a few guys were having discussion about harmonic resonance and marching on bridges. Two of the guys were sceptical. I told them we could prove it then and there. We were on the 7th floor of the Mega structure and we had an all steel cage stairway. We started marching in step in the stairs and eventually the sound resonating from the steel bars was unlike anything you can believe. At the bottom on the ground floor the steel handle was moving back and forth and singing an high pitch whine. The duty Sgt almost caught us. We probably could have collapsed the whole stair case had we continued.
An the same thing happened to the Millennium Bridge in London. I saw it from an interesting 5 minute video called “London Millennium bridge opening”. It was made in 2007 but still is pretty good.
@@aidanlanham8823 I remember, I believe they needed to make a few corrections shortly after the bridge opened. Now, if you can find 4 of your buddies, and you know an old building with a steel cage stairway and you want to hear something interestingly unique...
@@q_q123 That makes sense. Physics was a junior class at my old school, but a freshman class at my new school. I guess since I moved to the new school as a sophomore, I never had the chance
True. It happens to everybody. Because in high school, we were forced to study it but on TH-cam we're watching it with our own interest. It's not about age, it's about interest.
Cool Science Teachers: *creates awesome demos to explain physics etc* My High School (picture chadwick bosemans' black panther): "No, We don't do that here."
Ah yes, this appeared in my recommendation for unknown reasons. It is scary how TH-cam actually know what I enjoy watching without me even searching for it. This is just so satisfying to watch and I have no idea why
If you try you can notice the effort to swing increase with the frequency exactly like the energy of the electromagnetic wave ( ex uv has lower energy than gamma rays)
Fun fact, I learned while working on ski lifts that these harmonics are possible on a moving lift line (weather permitting) they often cause lift faults but could be so bad as to actually take out an entire lift line, luckily they now have pneudraulic and hydraulic automatic counterweight systems to relive tension and prevent these
I have a beaded curtain in the doorway of my bathroom. When I walk through the beads in the afternoon, the light from the window casts a shadow on the floor and I can watch the standing sine waves form and slowly dissipate. It's mesmerizing....
More importantly, the first 6 harmonics played simultaneously are a major triad. Fundemental, octave above, 5th above that, 4th above that, major 3rd above that, minor 3rd above that. Which forms a nice root position major chord.
I used this set up on paper to explain musical notes and octaves to my students. We derive musical scales from the natural harmonics that come from regular vibrations. We move those divisions up and down octaves to complete the scales. Making the new harmonics from one note into the root of a new scale produces every other note. I think the universe is made of strings and vibrations and energy moving through them. We love music because it is a direct line into the very fibre of our being. I think.
I used to do this with ropes when I was growing up, I usually spun the rope instead of moving it side to side, trying to see how many I could fit on the rope at a time, its cool to see this as a science demonstration
After 5th Harmony , I was like he can't do any more. Then it came 6th. That's it, it's the last one. Then I saw 6th, I was like what the hell. Let's keep open mind
The very first demonstration showed a traveling wave (like a wave in a pond) that is reflected at the ends of the rope. That's why it moves forth and back along the rope. The harmonics on the other hand are standing waves since their nodes are in fixed locations. Interestingly any standing wave can be calculated as the sum of two traveling waves that simultaneously travel forth and back. And that is btw. how resonance works.
Oh my god, I have been trying to explain this too my kids… this is what I used to do while I was talking on our land line back in the day. I was a kid and would stretch the cord as far as it could go to get privacy and pull back a part of the line like a rubber band and then let it go and watch it wave back and forth at me!
At the Austrian mountains, east tyrol, there are heavy thick steel ropes strained over hundreds of meters along the hills slope. At least, I encountered one such rope. If you pull it down fast, strongly and short near one end, the rope seems to not move for up to 10 seconds - then suddenly the wave will come back with full force like magic.
I just want to say how beautiful the universe is, in that we can make this wave. Light and sound do this and yet here we are, able to make it physical. Not only that, we can apply it to so many aspects
I used to be a physics teacher and that's how I started explaining stationary waves. I used to borrow a lan cable in the morning and tell the students that I beat the ***t out of the previous. Marvellous days indeed.
Reminds me of college when I did this with a small string and a vibrating device. Trying to find the right frequencies by tuning it. I think I took that class shortly after this video went up

Thanks u,bro
Knew it
Bud just learn urself what's antinode😂
Antinodes are points that Oscillate with "Maximum Amplitude".... All points other than the Nodes Oscillate
With Max amplitude..

Also gotta acknowledge how good his coordination is to keep the tempo

I'm 14 and I think this is just a demonstration of how different sound waves react when interacting with each other thus the term harmonic

Just woow. Love it ❤
I was searching for standing waves demonstrations, and trust me, this was outstanding
