- In this video I show you what it looks like when you reflect a true mirror (non-reversing mirror) in a regular mirror. I talk about if the reflection truly does go on infinitely. If so what is the area of the reflected images. Is it infinite as well?

Why are you gae?
The reflected light reduces each reflection and is passing more and more imperfections in the glass so eventually the image would be hazy Distorted and dim and you’d have aberrations. So the equations don’t really account for this and it won’t be truly infinite eventually no useful information is transmitted. So the infinite length is more of a theoretical infinite.
Moreover, for the number of reflections to be infinite, you'll need infinite time, so clearly, during any finite time, there are finite number of reflections.
I mean what you said is true
That's because we don't have ideal conditions. Math involving infinity usually breaks down when applied to the physical world, because it's not ideal. That's why physics books' problems usually start with "assume ideal conditions".
Also, remember, each length gets smaller and smaller. At a certain point, the length of the line falls below the plank length. At that point, QM kinda breaks down and the universe turns into a lovecraftian nightmarescape...
@@mitkoraichev3187 There are limits in ideal physics as well such as a plank time and plank length being the smallest unit possible. So we should still end up with finite numbers.

I love this video because it combines both simple and visually interesting explanations for people who aren't well versed in science and math, but it also has a bit more in-depth explanation for people whose knowledge is more intermediate. I think it is rare for education videos to fill both of those roles well. Usually, they are either a bit simple and childish or they are very in-depth and complex.
Thanks for posting this ActionLab! I always wanted to know how mirrors reflected and if they truly reflected into infinity... Brings back childhood memories of playing with mirrors as well! True mirrors reflecting into ordinary mirrors looked very interesting and artistic though.

That infinity problem is interesting, it reminds me of with the coastline of an island. It's infinite if you measure it infinitely exact (fractal). But the area of the island is obviously finite.
Addition:
The number that you called "some constant" is actually W*H*π²/8
I didn't get the horn part. You can't cover the entire surface in paint? What?
Yes you can, drop your horn in a tub of paint.
What am i missing?
@@cryptfire3158 the horn is infinitely big. You'd need an infinite amount of paint for that
@@huawafabe
If that's the case, why does he say it has a finite volume. Certainly i'm missing something, since i can't imagine something of infinite size having a finite volume
@@cryptfire3158 That's the reason it is so weird. But you can get an idea of why this is possible: Imagine slicing the horn up. Each slice has an area of πr² and a circumference of 2πr. So if r becomes smaller as you progress through the horn, the area of the slices becomes smaller more quickly than the circumference. It then happens to be that the circumference decreases just slow enough that it goes to infinity.
@@vinlebo88 it's pretty unintuitive, the easiest way is to look at it mathematically like he did. Areas that stretch out into infinity but converge csn often be finite. For example, the energy required to leave earth's gravity field is the area under a graph with that is a/r² (a is a constant). The graph never reaches zero, but the area is finite.
Another example that I already mentioned in my original post: if you measure the length of an island's coastline, you mathematically get to infinity if you measure totally exact (go around every tiny stone, or even every atom etc). So the 1 dimensional thing is infinite. But the area inside this infinitely long coastline is finite and has a limit 😊
dunno how "true mirror" works but would be kinda dope to see an array of true mirror and regular mirror
like, 100 tiles wide and 100 tiles high, where every odd tile is a regular mirror and every even tile is a true mirror
would be tripper
I did this about 10 years ago in my grandmas house. I didnt know about the different types of mirrors until now. Really looks like your looking into other dimensions.
I love these videos! Thanks for making them

Excellent comment!
Funny as fck!!
Plot twist: There is actually 2 person. The other is his twins
1:20 AWESOME EFFECT!! Inception !?
I’ve always wondered about this. If you performed this experiment for say 24 hours and then you removed one of the mirrors technically there would still be light bouncing but would the light be now bouncing in a different time and space?
further explain. Sounds interesting.
Now I ask myself "What would it look like to have 2 true mirrors facing each other?"

Man this is so cool! I love how surprisingly awesome physics is! You make great vids fo sho!
wow that is way crazy and yet interesting, good job!
I started wandering: what would a reflection of a true mirror in a true mirror look like?
Apparently nobody cares or it is too painful to think about
Same as a regular mirror but the image would not be laterally inverted.
First thing I wondered too....
Funny how the silver itself on the glass reflecting is similarly going within itself to infinity, but not the mirrors, in this dimention the reflection stops at the last molecules able to reflect.
0:30 "a regular mirror does not reverse anything". Wrong! A regular mirror does reverse front and back. And because we have symmetric face and body, we think that it does revert left and right, but not top and down. Which is wrong. A mirror does not reverse left and right, nor top and down, but only back and front.
You have some awesome questions and answers to the mirror effects!
I would argue that the answer is a definite yes. I think a good interpretation of whether the image goes on to infinity would be its distance from the viewer. Since that is a length amount, that goes to infinity.
Does the size of the mirrors affect how much infinite mirrors you can see?
If the image is getting smaller every reflection, it can’t be infinite.
At some point the image is smaller than the wavelength of the light and won’t be reflected anymore.
Also light loses a tiny amount of luminance when reflected, even off of a mirror.
I would be interested in whether you could get a see through mirror, and observe how far down the rabbit hole we could see. Also awesome video.
When I was a kid I scratched off a tiny bit of the silver coating in the middle of a mirror so that I could see through it, but it wasn't obvious from the other side. Then I put it opposite another mirror, and was able to look through the middle of the mirror rather than around the side of it, which usually makes the 'tunnel' curve off to the side and out of view. You can see a lot further, but as you'd expect the image becomes more blurry and darker with each reflection until you can't make out any more reflections. It also becomes more green with each reflection as glass is slightly green in colour, as you can see if you look at the edge of a sheet of glass.
So, W goes to infinity.
And H goes to infinity.
Area is finite.
W x H = A. => infinity x infinity = finite.
I can appreciate the calculus involved, but what you didn't use to limit the series to keep it from continuing to infinity is the idea of a smallest possible reflection. I pose that this limitation would be reached when a single photon is bounced, since a single photon is the smallest unit of light. It would not preserve any physical resemblence to the image because it would be akin to reducing a photograph to a single pixel, and we wouldn't even be able to say with any kind of certainty what wavelength that quanta would be traveling at because of scattering and such. But I digress. Placing that single limitation removes the latter portions of the series that could yeild and infinite result.
Great video and I really like the images of reflecting a true mirror onto itself.
Notice how the reflections get darker as more reflections are reflected. You can see the opposite happen when aiming a camera at a monitor displaying an image from the camera. It gets brighter. I wonder if you could balance the lightening and the darkening effects by aiming a camera at a mirror reflecting the image of the monitor which is displaying the output from the camera....or maybe that's when we break the universe and the ending credits start to play.
In fact it's finite because at some point it runs out of light to reflect.
The mirror is absorbing part of the light at each reflection.
Adding the fact the area gets smaller as well.
This is the first time I don't understand what you're talking about in one sitting. I need to rewatch this a couple more times lol
It's simple every time the surface becomes half of other e.g If I subtracted 0.5 from 1 and then goes on there will be something left to infinity unless you subtract whole number from it
You have to get animator for your self so ppl can undrstand even more.
gabriels horn: paint... the paint is than assumed to consist of infinitesimal small paint molecules and they are not. theyare at minimum a few nanometers big and the horn goes to infinite smaller widths going to infinity
wait so what would it look like if you were on the inside of a sphere mirror. like the you're inside of this sphere the whole around you is a mirror but would that look like. Sorry if I didn't explain well
Correct me if Im wrong, but I think the argument used to prove that the images dont go forever is flawed. A point is made that an infinite set does not contain infinite elements because the sum of them converges, which really has nothing to do with the number of elements; which is by definition infinite. In other words, it is already being said that the sum has infinite summands, and the summands are the number of areas, so there ARE an infinite number of areas, it just so happens that the sum of them converges to a finite value, because the area decreases quadratically instead of linearly as the length does.
Man, I love this channel.
Whoever said, that science is boring - apologize now. XD
I think it was Einstein, who said, that when you can't explain a complex problem with simple words - you don't fully understand it yourself.
Late Stephen Hawking was a genius exactly because he could explain anything even to a biggest mathematical imbecile (like me).
This guy also gets it.
Problem with regular education at majority of schools is, they just tell you to memorize some definitions and formulas, but they won't give you much explanations, which are simple enough to be understood by anyone (like some real-life examples of given phenomenon or possible practical applications).
It's one of my favorite channels as of now, waiting for new content!
I was wondering what the last imagine would be a few days ago in an two parallel mirrors so it’s kind of coincidental that this video exists now
I like your experiments a lot!
The laser part at the end was awesome
All videos should be 10 minutes of mirrors and lasers.
That the total area is limited does not mean, that there is not an unlimited number of reflections, because the total area can be divided in an unlimited number of areas.
I've ALWAYS wanted someone to put a camera behind a 2 way mirror, then face another mirror so we can truly see how infinite a mirror goes!
Well, it's a nice video but I'm sticking on to my 100% flat ,shiny and exclusively regular mirror for now !
every time he says "in real life" as if a mirror image isn't a thing that occurs in real life lol
The only reason it's "no, it doesn't go on forever" is due to the inverse square law that our vision cone introduces, i.e. lenticular field of view. A true orthographic projection and reflection in any mirror would go forever with no inverse square law.
thom1218 Perfect mirrors*. Because mirrors that we use in everyday life absorb a small amount of radiation with every incidence upon them. Vsauce explained this showing that mirrors absorb green wavelengths the least, causing the further reflections to be progressively more green
I remember having a problem with Gabriel's Horn back in high school... The math works out, but the "paint" analogy isn't intuitive... If you "fill" the Horn, you would coat the inside, which is the same as "painting" the outside (which has to have the same area as the outside because it has no thickness). The analogy is difficult because we are mixing real things like paint with theoretical things like surfaces and infinity.
Would this also be so if it were a true mirror into a second true mirror rather than a "regular" mirror?
Dude I have got a doubt, what will happen to light if it is trapped (enclosed) inside a cube made of the mirror (inner part), will the light remain there forever reflecting?🤔 Hope you got the question.
It’s “countable infinity”. As apposed to “uncountable infinity”.
imperfect reflections and dirt on the mirror also diminish the distance you can see, much like looking through fog, therefore it is not infinite.
Another fantastic video. Thanks for all your work.
I'm not sure if you're describing mathematical limits correctly. One just converges on a limit a lot faster than the other. But both are an infinite series.
Okay you need to do another video about that Laser! You can see where the reflected beams cross. It's super bright there. I wonder how hot it is.
Hey.. I have an idea for an experiment
-.what would happen if you shake soda then place it in a vacuum?

@@jetnut89 ow thanks man
And also, in case of Gabriel horn if you consider the paint covering the surface area has 0 thickness (which you have to...) Then the volume of the paint will be in 0 x ∞ form which could be finite (Actually in this case it could be infinitely small finite value closest to 0 (hypothetical value); So the volume π automatically exceeds it...) in some cases (in other cases it also can be 0 or ∞, it depends...); So finite paint π unit^3 which is filling up the volume, also covering the surface Automatically by default; So it is also not a paradox At All
You answered the question "do the images go on forever" in a theoretical way but not in the real world. How many images can actually be seen? I know it would depend on several factors but what would be the most that could possibly be seen?
Something important to note about the area; while the number is finite, the actual value infinitely approaches that finite value. To simplify the idea, take X < 4. X infinitely approaches the number 4, but never reaches it. You can have an arbitrarily large decimal place, infinitely long, so long as X is never exactly 4 or above.
The same goes for the total area. W*H*(1 + 1/3^2 ... 1/n^2)
The variable n is the number of reflections in the series, and this series is infinite. The further you take the series the closer you get to an exact value for the total area, but you can never actually reach an exact value. Like the value of pi, this is an irrational number.
Question, if you get multiple mirrors and make the reflection side facing in words will it reflect the last thing the mirror seen?
You probably won't see this
So, I get that the mirrors reflect semi-infinitely *mathematically*, but what do they do physically? Photons have a finite size, as far as I recall, and the mirror's surface does have a finite amount of "smallness" it can have (the Planck length). Plus, the mirror is going to absorb at least some small percentage of light, so with each generation, the reflection should get darker and darker until it dissipates, presumably long before it hits subatomic scales. Is my guess accurate, or am I missing something?
For the most reflective mirrors ever made, small things in the reflection could be below molecule size before the image would be too dim to see, assuming we're doing this in a vacuum so there in no dimming due to air. In that case though, I strongly suspect the imperfect flatness of the mirrors' surfaces would come into play long before that point.
"Today we're gonna be shining a meer into a true meer" ha ha ha
Thank you. Now I can only hear him saying meer
The area would become to small to sustain photons so no the image stops at a certain point but the division goes on for infinity.
That only works on a theoretical sense, in reality the width is finite because you can only go as far as an eletron can reflect from. I mean the universe is granular and not continuous so that "infinite" small area will stop at something like the plank's lengh. Or will it? (correct me if i am wrong please).
It should be noted that this applies only if the mirrors reflect 100% of the light. The best mirrors are silver and they only reflect about 95% of the light. Thus, each image is about 5% dimmer than the previous one, and the images become undetectably dim after a fairly small number of reflections.
I'm missing something. What's the point of summing lengths? How does that help us in understanding what's going on?
You can not break the Matrix!!

UNLIMITED POOOWWWEEEEEERRRRR
Awesome video - thanks for posting!
The answer is no because at every reflection the mirror does not perfectly reflect all the photons. Some pass through the mirror. You can see the fade as you look into the distant reflections. The fade is not all from distance, some of it is from photon loss.
In other words no mirror reflects 100% so the loss of all light happens at a particular distance. Would be interesting to involve a telescope.
Where so you get a true mirror? Great video with a lot of information.
I'd say its not going on forever. The mirror absorbes a small percentage of the reflected light. That's why the created mirror tunnel looks kinda faded in the distance. Let's just say after each reflection it absorbed 1 percent of light. Then we got max 100 reflections.
Actually, at the 100th reflection you'd still have around 36.6% of the light since each reflection will only absorb the light by 1% of its previous reflection. At 99% efficiency, it'd take around 450 reflections to get to 1% just from the reflection alone.
@@Taikeb0 oh okay, thanks for your correction. 🙏
So the question is - If I performed this experiment -considering there can never be instantaneous transference of imformation - would my infinite length or height image remain indefinately even if I moved away from the mirror ...
This got me thinking it would be cool to see how far in you can zoom with a good lens. The real limitation is the quality of the glass, the image will start to fade the more times it has to bounce off the mirror.
Needed to be added that mirrors don't reflect 100% of the light. So all those reflection loses will "eat away" the light that is reflected numerous times. That's why the farthest reflections in series look darker.
So, at some point in that series, all the light photons will be absorbed. Totally, because at some point there can not be 1/2 of a photon left for example. The reflections won't go to infinity.
I think that "quantum reasoning" will make the length not diverge. At some point, the smallest width length stops at wave length of the reflected light, so it's a finite series.
If you face 2 mirrors to eachother and you place an object in between, why does the image disappear when you remove the object and not stay in the mirror because the reflect eachother.?

Great stuff - I like these videos. He makes them fun and you learn things along the way. Like Mr Wizard back in the 50’s 👍👍👍 (I’m old👨🏼🦳) Thank you !
And of course practically speaking, the glass absorbs a little light at each reflection, thus dimming the images progressively to nothing!
“Is the image in the mirror infinite?”
“Well yes, but actually no”
no, it is.
yes, it is not.
make a horn of finite volume with a semi permeable membrane and then fill it with paint inside since it has a finite volume then paint will seep out and will paint the whole surface area.. is this paradox solved 😁?....(i think i painted something which is impossible to paint).. say yes coz i m already feeling like eienstien
Wiki has the answer. The painters paradox is resolved by realizing a finite volume of paint can coat in infinite surface by decreasing the thickness of the coat of paint by an increasing rate as the surface is painted. The series would look similar to the series he showed for the surface area of the horn.
You're explanation is really very good
Pretty cool! I love learning stuff like this! Please keep it up...
You actually cannot fill that tube with paint in finite time, since the velocity of filling will tend to 0.
You should look through a one way mirror at the true mirror. You wouldn't have to worry so much about you and camera being in the way and you might get some really interesting view on whatever objects you put between the mirrors.
Hey I want to know what happens when you rotate a true mirror relative to yourself. I’m guessing it rotates opposite to the rotation of the mirror which would be trippy.
This is some next level inception for me !!
I would argue it doesn't go to infinity, as at some points the last photon will be absorbed by the mirror surface or scattered somewhere
How did you get 3d for the second reflection? And why do those correspond to distances of 1/3 1/5 ... ?
When people ask "does the reflections goes forever" they don't care about total length or area of reflections. They care just about pure number of reflection! I mean will the reflections stop after 100? Probably not. After 1000? You definitely won't see that many reflections, because they are going to be to tiny, but they are still there! So... is this a limit of reflections when put this way?
