But.... It's the stuff around that nothing that makes it colorful, or at least the interfaces between them and nothing. A thin slice of nothing between air is not colorful.
Don't care,plus I make better content I was just joking 👑 king,you are worth more than your looks and sometimes it's okay to be ugly❤never give up Was joking again you are good looking Nah I don't think so,that's a joke as well😂 Don't take my comment seriously it's a joke😂
"A thin slice of nothing is colorful" strangely poetic because it means even though our life is mundane, at the very core it is very beautiful and as stated colorful.
Yea, it's kind of a philosophical sentence. a lot of them seem absurd up until the moment you can relate. Then your like, "oh my gosh, this whole time" I like to find meaning in words instead of discarding them like trash. Especially when it's something you know makes sense and you can make a meaning of it.
It's because it is absurd. You aren't seeing the 'color of the layer of nothing'. You're seeing the same principle he just explained happening between the two inside edges of the glass plates.
this principal is also used in manufacturing optics / lenses. the bands are called fringes and their size, space from eachother and concentricity can be used to measure surface quality, radius or flatness of a surface. i got pretty used to looking at these patterns daily when i worked in CNC optics. pretty cool stuff. for anyone more curious, the measuring process we used was laser interferometry. :D
@@CharlemagnePetrieAt that it's just the light interfering with itself as it bounces back and forth between the glass. The "nothing" is simply the "really thin"
A thin slice of nothing is colorful, sounds comforting due to the mind subconsciously breaking down the words into an equation like subconscious thought, in the equation like thought it removes the words "A slice of" then goes to the word "nothing" and it thinks of "colorful" as something, then thinks of that entire part and thinks something is equal to color and then thinks nothing + color is equal to something due to color being a thing. Then the mind relates itself to something as We are something. Then it goes to "colorful" and relates a color it thinks to be beautiful to colorful After the mind is left with the idea that Nothing + Something = Ourselves + Color = Beauty
Using this phenomenon, thin films (100s of nanometer thin) can be measured by eye. Accuracy might be somewhat lacking but it's a neat trick when eyeballing silicone oxide growth
This will come in so handy all the times I'm growing silicone oxide in my day to day. I'm so tired of feeling like the silicone oxide is going nowhere (much like me, an avid silicone oxide cultivator).
True, I installed a new ALD machine to grow aluminum oxide films and the color of the reaction chamber changed over time. But this is not very practical for films with only a few nanometer thickness, these are transparent
@@thatonespooder1513bro I started questioning myself that too 😂 honestly it took me 20 seconds staring at the wall 😂 but as a person who loves literature, I appreciate every word especially some sentences that doesn't even make any sense 😂 it's just that you gotta find the meaning of it for yourself, depending on how you see it
it's not beautiful or poetic, or even interesting(because it's nonsensical, and there is little novelty in nonsense beside the fact that it IS nonsensical). it's pathetically unintelligent to rave over such a simple sentence. i can think of rather significant things which you probably don't consider poetic in the slightest. but hey, we cannot all be intelligent. it's ok.
@@josepedro335Probably because it comes across as super "uhm actually" and kind of annoying, like when someone says black is their favorite color and someone else points out black isn't a color. Everyone understood what he meant. There's no need for meaningless corrections
@@AverageSeaMonster In this case I think it's different because it can be misleading. It makes people think that nothing as a color, while nothing is nothing, it can't have a color
@@josepedro335 It's not really different though. It takes two seconds of thought for someone to understand that him saying the slice of nothing is colorful isn't accurate. I promise you, it doesn't take a rocket scientist to figure this out. This video doesn't need people pointing out what is pretty obvious
@@AverageSeaMonster When a video is made with an educational tone, people will often believe anything. You'd be surprised at how often an "uhm actually" is completely necessary
Whilst poetic, wouldn't the surfaces of the glass being close together be doing the reflecting (the inner glass surfaces act like the outer surfaces of the bubble?) here and not the air/vacuum?
There is no difference, the first surface reflects some light and refracts the rest, which then reflects off of the inner surface. The phenomenon is called thin film interference.
Yes, but the medium between the two pieces of glass is necessary for this effect, whether this medium is a vacuum or air or something else. Need the different speed of light on the medium between the two glass surfaces to refract the light ray that reaches the second surface. So when it reflects back to your eyes it is slightly different than the reflection of light from the first glass surface. Creating this interference pattern.
With the bubble, you have 1 kind of surface with 2 faces. With the air and the glass, you technically have 2 kinds of surface and 4 faces: two glass surfaces contacting the air, and two air surfaces contacting the glass. This makes it confusing because it’s unclear which of the two surfaces in the 2nd case is doing the reflecting. I would think it’s the glass doing the reflection, so then of course the air and the vacuum result in a similar effect - but only because neither of them obscure the reflective effect caused by the two glass surfaces. Am I missing something ?
Once you learn of thin film interference you’ll notice it in a lot of unexpected places. Like blued steal. Or when a crow or raven flies by and the sun hits it just right and its black plumage turns iridescent blue. Well most birds really. And lots of insects use this physical property to give them color without pigment. Like butterflies.
Many of the animal examples you provided are actually interference, but not thin film interference. They are usually more akin to the way opalescence works.
@@sophiophileis it true about what mentioned in the beginning of this short that a colorful bubble is because air trapped between two layers of water? Isn't it because the thin film interference between the oil layer of the soap and water? Please answer

These are called moire lines and are a pain when you have old camera film youre trying to scan - if the film is up against glass then you get these unsightly bands in the scan.
not exactly, while a moire pattern looks similar it actually refers to two misaligned grids. you'll see this if you take a photo of a screen where the grid of pixels will be misaligned with the camera sensors' grid
Newton Rings get removed by using Anti-Newton Glass, which are lightly etched on one side to deform the surface enough to prevent this but with minimal effect on image quality.
So i made precision optics for 14 years, and if you have a piece of glass that is a known flatness or curve, you can use this (or at least a similar ) method to find the the flatness of another piece of glass in relation to the first
So i already add a reply to this, idk where it went. But it was just a family business, we made them for all sorts of thing. They're in more than you would expect
What’s important here is not really what’s between the slices of glass. We see colors because of the interference between light rays that are reflected by interfaces which are separated by distances around the order of the wavelength. In any interface that separates regions of different index of refraction, you will get what’s called Fresnel reflection.
I'm not usually a fan of Shorts, but am always glad to check out ones from the action lab. The titles are straight to the point, and in the limited time he has he always shows some cool, self contained phenomenon or tidbit. Hell yeah! :D
depends what you mean @@sogga_fan i meant that those bits of info are often interesting, and varied in a way that feels rewarding to curious folk, i'm not comparing full vsauce episodes to his shorts, that would be unfair. it's a different format and intention - but the drive to share lesser known facts and shed light into things we don't normally pay attention to is clearly there
@@oowazhe doesn’t do enough research and gets things wrong all the time, also he does pointless things that confuse people just to get a clickbait title(like putting this in a vacuum) Also he has no testosterone and I can’t stand him
How does vacuum refract? I would have thought since there was nothing for the light to bounce off of, it would not refract. Would the light be bouncing off of the second layer of glass, instead?
@@lolwtnick4362 light is all you can see. That's what eyes do, they detect light. You can't reflect what you can't see. That wouldn't make sense. Reflecting light outside of the visible spectrum not withstanding
Refraction happens at the interface of two mediums. That medium can be a vacuum. The reflection isn’t just happening on the glass it’s happening due to the interface between the glass and the rarified air (vacuum).
@@ActionLabShorts That makes sense. I guess it’s confusing because generally we assume that things that are plainly visible are surrounded by air or something of similar refractive index and thus omit it from communications even though it is relevant. This creates a situation where “thin film of x substance” is a relatively complete communication while “thin slice of air” is missing the context of glass surrounding it. If you were to refer to a standard optical prism as “a triangular prism consisting of not-air” then you might get comments saying “but you didn’t mention the glass..”
“A thin slice of nothing is colorful”. This quote can be used for so many philosophical terms or phrases lol, like how even if u have nothing in life and feel empty and drained you still have something. In some way it brings a whole new meaning to “enjoy the little things in life” as even the small and often pointless things can bring joy and or can be seen as beautiful.
THERE ARE "THINGS YOU CAN'T SEE", JOUSUKE... THEY'RE SOMETHING THAT DOES NOT "EXIST" IN THIS WORLD... BUT THE FACT THAT THEY DON'T "EXIST" MEANS THAT THEY CAN GO BEYOND REASON! THEY'RE "DIFFERENT FROM THE VISIBLE SOAP BUBBLES AT YOUR FINGERTIPS".
@24kanthony what's the point of this comment? Are you hoping to change both my thought process and the conclusion I draw from it? Because if so, you failed miserably. That means I can only assume you did this to exert some form of power over someone random, and that you perceive to be wrong or insignificant, because you are so insecure and beat down emotionally and spiritually on your own day to day life. Do better homie. Comments like these make it look as tho you have an ugly soul. Maybe you do, but I hope not
@@24kanthonybased on what. Since you said that you must be very knowledgeable about science yet you provide no proofs of anything while using biases to put out false assumptions
@@24kanthonyPerfectly true ! These videos are only apparently scientific, in reality they are made for "fun". Today's man must be "entertained" in all ways, including by force !
"Air and vacuum have a similar refractive index..." I know what you mean, but it is really to hear you refering to low to almost 0 density area as being made of some material called vacuum. It is basically rate the speed of light travels through a region of sapce taken up by/surrounded by matter, and since the air barely changes that "speed", it works about thd same.
