Making standing waves
Вставка
- Опубліковано 29 сер 2024
- A standing wave is made by sending a wave group down the tank against a fixed wall. The reflected wave will superimpose upon the incident waves doubling the amplitude. As the wave maker imparts more energy in to the system, the amplitude increases. The waves are sustained by gravity and hydrostatic force and dissipated by fluid viscosity (the frictional forces against the wall are negligible). The video has been edited as the clopotis and seiche that occur last over a half hour and are eventually killed with the wave maker acting as an absorber, as it tries to produce waves offset by one half period of the waves hitting it.
i love the youtube-2009 white letters on blue background look, just missing the background track 009 sound system - dreamscape
Ik ook
That was surprisingly fascinating and intriguing to me. I particularly liked watching the waves gradually bouncing back and forth as the force slowly diminished. You could clearly see the difference in height moving from one end to the other, with the calmer water at the opposite end.
it really cleared my concept of standing waves
Should float ping pong balls in the water! It looks cool, but it is hard to tell if the nodes are truly stationary. Must be extremely hard to tune the waves i n a large tank such as this.
verdade, tbm vim pelo coruja games
@@dogowo what the duck you said?
@@rovstam7989 According to Google Translate, they said in Portugeuse "True, I also came for owl games" which still makes no sense
its incredible to see the optical illution it produces, by not knowing which direction the waves are going
Yes! In terms of electricity you could easy do this with an A/C signal and a pulsed DC signal. Standing waves in electronics are due to harmonics(something that is usually thought of as bad). They are called scalar waves with EM stuffs. Look up Hutchison for more stuff on electronic harmonics. Standing electronic waves was Tesla's most important discovery(to him). Be careful and Have fun. :-)
Yes, The hydraulics are controlled with a pc using a widows based program that allows period and wave height to be input. The software was developed by MTS which also build the wave maker
please film this again but in 1080p :) that would be so cool and satisfying
low frequency sound (subwoofer) exhibits very similar physics behavior. Switching the phase in / out can cause nodes or nulls in different areas of a room.
physical matter is the "standing wave" of light.
"moving" light is just an "illusion" just as waves moving is an illusion.
Rather...light doesn't move...…..it STANDS STILL!
if we take a rope and move it up and down to create a wave..is the rope moving?
no, rather, information is being PASSED along the rope.
we are created BY the light.
we are TEMPLES and CHILDREN of this light.
no phase switching needed since the walls produce nodes and nulls. you can easily find them with this: www.szynalski.com/tone-generator/
a fun thing to do once you find a node es to walk around in the room and see the loudness change a lot depending on where you are
Woah
this is really satisfying
Industry...Science...and Technology...Finding a way to end the kiss of Poseidon whilst sitting on the toilet. I wish I had a pool like this.
This is really cool,
I would be so damn happy if I had this kinda experiments in my lesson!
Watching this while listening to trance is more fascinating than it should be.
For Plengo: Yes these are standing waves. The key thing is the length of the tank is much longer than the wavelength of the standing wave. The tank is a transmission line and you need a transmission line to make standing waves. In the LC resonant setup in the generator coils the wavelength of the waves are thousands of miles. Like Itsu said, you are dealing with lumped elements in the circuit, not a transmission line -> no standing waves, Bolt is wrong.
Hank they are called standing waves caused by extremely low frequency low amplitude waves. Their shape is dependent on the shape of the pool.
It may be due to a nearby pump, heater, or AC unit. I would guess the pump. They can exist anywhere, but the wave source must equalize with the body of water... which is unlikely in nature. Maybe a cenote and a consistent wind speed over the mouse of the cenote. I would think calm pools would be the only place you would notice it.
It seems like this video finally hit the UA-cam algorithm and rightly so
The distance between two nodes depends on the frequency and amplitude of the wave. However, the formula for finding the distance between two nodes is λ/2.
Looks interesting, but I wish there was better real-time narration to explain what changes were being made, and how those seem to be causing the phenomenon we observe in the video.
Wanted to give someone a quick look at what standing waves are. Very important concept of physics. Thanks for posting :)
@suleydaman It is easy, the students in the back ground are all English, Poly Sci, History,etc majors. They are being forced to take a class on ship stability and most hate it, but they are to be naval officers , so they gotta know something about ships
In fluid dynamics, Airy wave theory (often referred to as linear wave theory) gives a linearised description of the propagation of gravity waves on the surface of a homogeneous fluid layer. The theory assumes that the fluid layer has a uniform mean depth, and that the fluid flow is inviscid, incompressible and irrotational. This theory was first published, in correct form, by George Biddell Airy in the 19th century.

@Kenoburned it's no illusion, as the oscillator builds up to the point where the wave starts to stand, the peak of each wave is moving towards the camera. Once the Oscillator is turned off you will see each wave produced dissipate one by one and it will trail back and forth in the tank, like the ending of a musical round.
There'll be circles with their center moving downstream. If the velocities are equal, the rear end of the outermost circle will stay in the drop point.
Clap is by definition a sound of the air in an air pocket after it abruptly changes its form and/or size - especially, one between two striking surfaces. So depends on what you clap it against but largely the same. Is likely to be muffled by a louder striking sound.
I find standing waves to be quite fascinating
Just like sound waves can be used to neutralize noise in a car or plane, maybe liquid waves could be made to counter a tsunami. Just a thought. Generating the counter wave may be tricky.
coredor the energy needed to counter the tsunami wave would equal the energy contained by the tsunami wave itself. so i think that would be a very powerful, large-scale machine
That's so creepy. I am too afraid of water to work at this facility.
That's a cool name for a wave that is standing
yeah
@Moue666
Amplitude: The "height" so to speak of the wave from equilibrium. Ie. The distance from equilibrium from the crest to the eq. point or the trough to the eq. point.
Wavelength: The distance from one point on a wave to the exact same point on the next wave
Wave-number: 2pi/wavelength
Period: The time for one oscillation to occur
Frequency: the number of oscillations over a given amount of time (reciprocal of period)
Angular frequency: 2pi * frequency
Velocity: The wave's speed
Further, several second-order nonlinear properties of surface gravity waves, and their propagation, can be estimated from its results. This linear theory is often used to get a quick and rough estimate of wave characteristics and their effects.
I think I have seen this on lakes. It's when there is no wind and the water is just sorta vibing.
@ValmisFilm No, there isn't any water flow from one side to the other, so the boat would simply oscillate up and down.
Quoting Hoptoad: "the term, bloch wall, is readily accepted as referring to the "null magnetic region" in a magnet where N + S vectors are equal, and cancel out. Also often referred to as the magnet's neutral region."
He is incorrect. There is no "neutral region" inside a standard bar magnet and there is no Bloch wall. There are no "N and S vectors." I suggest that people go back to basics and look up how a magnet works.
If I share this out of context in tiktok they will say glitch in the matrix 😂
Peak becomes trough and trough becomes peak
Interesting experiment, especially if you think that it is only true when you see the equations making it happen. The direct physical experience is very very important here. Good video!
Thanks, now i understand interference! that's great!
Are there any emotional changes going on with the people in the lab when they do this?
And you please put a linear stroke converted to rotary motion and use a small portion of the energy to maintain the propagated waves?
And how much power can you's make? Over the costs...
And can you minimize the energy required for the wave maker when it's up to speed say like a 10% to maintain the wave? Like a gravity assist 😁
Actually you could use a flywheel mechanical battery and use that to matain the wave and a electronic clutch ? Maybe or not needed I don't know, just when can reach wave resonance Will have the minimum cost and the least effort
Really want to see this !
Would be like a steam engine but without the steam and fire, and deaths etc
🤔 Oh that won't work, that classify it as perpetual motion 😕 nevermind
@ValmisFilm
no, that's why it's called standing wave.....it only oscilates, but it doesn't move.
This is so trippy
So if the natural properties of water is to seek and find its own level then undisturbed it would be flat and level correct ? The earth surface is mostly water so how the hell would there be such a big bulge of water in the middle of the oceans and seas ?
How do these guys act so casually when something so cool is taking place!!!
thanks for posting this!! looking at its formation is clearer to undertand
@gothaar Theoretically yes, what you are describing is a 1-1 mode.
Wonder if the magnetic field of a permanent magnet is just a standing wave field.
MTS wave board -- a big vertical panel at the end of the tank that pushes back and forth hydrulically
Any chance of a newer upload of this in higher quality? I love showing my students this video, but 240 is rough lol.
Would it be possible to jump in and swim? Or would my body disturb the resonance too much?
Very cool
ive never heard waves this silent wow thats cool ive done this in my bath tube before but i could only do it once or twice at a time then i would mess up but this is continuous
That wouldn't have any visible effect. The "Eigen" frequency of water is much to low for that.
Awesome vid, would be cool to have some water dyed so you could actually see more clearly what the water particles were doing
I would've prefered to have the camera mounted at the mid point and perpendicular.
that's sweet. We're talking about this in water resource engineering. Is there ever a time in nature that this occurs (due to some natural force?)
That's sweet though, this makes alot of sense
i know this vid was made a long time ago, however if anyone has access to this facility pls show what happens when a standing wave pattern is formed, then the machine is ubruptly turned off. Is there a surge of water to one or both ends?
Hey, noticed this is an old question xD Sorry no one has got back to you. I don't know what would happen for sure but I think I can make a decent assumption. If the machine was turned off the water at higher elevations would crash down and fill the lower spaces until the gpe of the water was evenly distributed. One way you could imagine it is a fish tank with one half of the tank filled to the top and the other half empty, the water would just flush to the other side.
Although it's a very basic explination I hope this puts you to some rest :)
A large rock is thrown into a river, creating waves on the surface of the water. The speed of the river
current is the same as the speed of a wave in the river. If you are standing on the bank of the river, what
will the waves look like in the downstream direction? How about the upstream direction?
is the water moving in this state? I mean if you would but a little boat on one side what wpuld it do, get to the other end or just o up and down with the wave?
Fun thing made by scientists!
I use to call these types of wave woof was at 4yrs old.
that looks soooo cool
Holy shit that is cool, the water is dancing
what else would you want. You just need to know the length of the pool and the speed of waves in water surface, and adjust the frequency to how many nodes you want.
This is some damn good acid.
The wave remains in the same spot because the water is moving along the channel at the same speed the wave is moving upstream
Jose Amador The water does not move with the wave. The water molecules oscillates back and forth and do not move like a flowing stream. The water molecules speed up, slow down, stop, change direction, speed up, slow down, stop, change direction again... This is repeated over and over.
that looks hypnotising
whoa
put a rubber ducky in! Now!🦆🦆🦆
I'm listening to breaks and the waves are matching the beat, totally cool... how the hell can they get the wave to be huge on one side and totally flat on the other
That also works with air molecules, but I wonder if it would work with LIQUID MAGMA?
Nice
So, can there be antinodes at both the end ? Since these are water waved...
vim pelo canal do coruja games
@froudedude If I wanted to make a wave pool like this in a park, would that be possible? would I just need the pool and a wave maker? thanks
It's beautiful
i approve of all of this
I've seen those types of waves in lake Michigan.
+Gabriel S. No you haven't lol the water must be trapped in a long canal, where the wave is forced to travel one-dimensionally. If the wave is allowed to radiate outward in two dimensions, like in a lake, it will dissipate. . .
+DarthHater100 Sorry but Gabriel isn't lying. Gigantic Seiches/Standing Waves happen in the Great Lakes relatively often. It's this but on a scale thousands of times larger. And a few times slower.
It really fucks everyone's shit up.
Looks like all people in laboratory are wearing the same sweaters, pants :). Look at those two on the left hehe :) FUNNY
Funny waves take my soul
Is only me sometimes felt waves changed direction. Is that a illusion?
yes
what is the sound of one hand clapping?
Is it fair to compare this with soundwaves? I have a test on this subject soon, please help! XOXO
ummmm,... soundwaves are longitudinal. so maybe not.
imagine being a fish in that... fun!
Jeez, look at it go even after the generator has turned off!
very sympatic
so nice
Might be a silly question but how much room is required to make a standing wave?
Theoretically, any. You can create a standing wave on a string of any length and given a water tank is the same principle, the tank can be any size too :)
@@George-ky2nv That was beautifully explained my friend haha thank you very much! I appreciate the reply. I'm currently exploring natural phenomenon within Loch Ness, those waters are incredible!
@@TeamLNE That's awesome man! Keep it up:)
@@George-ky2nv Will do mate! All the best 👍
Seems like water's marching left and right.
@froudedude
what type of wave generator did you use to create the wave
I would love to swim in there while the standing waves are been generated..=)
made it by computer?
can you make it 2D (like by imposing an identical wave in the orthogonal direction)?
Awesome
weird homework but okay
isn't a battery a standing wave in a portable carying case?
@suleydaman
It's so weird how many times people on YT write the exact same thing you were thinking..
I wanna swim in it
+DelzieC me too
you would brake the wave I think :c
u r idiot . the waves would not be affected if the waves r enough big..but it will get affected if you drop in this.
anvay gharat don't be so rude
@@ag5019 When you jump in the water or swim in it you create your own waves. That would drop standing wave out of balance.
love it!
Best regards to Mr. Zbyszek!
What's the difference between seiche and clapotis?
it would be so fun to go in there
No scientist refers to them as scalar waves. They're standing waves and have VECTOR and SCALAR properties. How can something with a vector be called a scalar? Do you know what a scalar is at all? It's a value, a number. Temperature is a scalar. Waves are phenomena that have scalars and vectors. IF you don't know these basics, you can't comment this properly.
"Scalar waves" is a pseudoscientific concept used to construct conspiracy theories and magical "healing" stuff in the New Age fandom.
