Total Internal Reflection Demo: Optical Fibers
Вставка
- Опубліковано 29 сер 2024
- This is a demonstration of total internal reflection in various types of optical fibers.
This demonstration was created at Utah State University by Professor Boyd F. Edwards, assisted by James Coburn (demonstration specialist), David Evans (videography), and Rebecca Whitney (closed captions), with support from Jan Sojka, Physics Department Head, and Robert Wagner, Executive Vice Provost and Dean of Academic and Instructional Services.
UA-cam recommended me at the end of my graduation right after four years !! Yeah,cheers !!
Congratulations I guess
this is taught in schools bro.
@Arian Orange I have that bruh...Thanks for concern btw 👍
Sad
I remember you commenting on some other channel's video. Coincidence!! 😳😳😳
Thanks, all!
Thanks 2 u sir
U r gr8
You are welcome
I like it
Oh man thanks to you for making such an informative video
This finally helped me to understant what optical fibre actually is
Hi
Same bro. It's ok.
so what you were thinking it is
Sahi kaha 👍
❤️❤️❤️❤️❤️ua-cam.com/video/K7Z5-NJc9qs/v-deo.html
Rules for total internal reflection to happen:
• it should always be from denser to rarer medium
• the angle of incident should be more than critical angle
@𝐿𝑜𝑣𝑒𝑟𝑖 😅😅
PW sir
✅
What happens when we put light from rarer to denser medium at such an angle which cause the angle of refraction be 0 degree or less than that?
@@MohitKumar-zc8pc then there is no Total internal reflection
It's funny to think that the video about total internal reflection was probably sent to your router via total internal reflection ahah

Only a few who thought about it. Remaining are just consumers just like me
Yes that's why he made ammunition, bombs, dynamites, explosives. By which he has the power to kill himself. Really human mind js awsome.
Where can I buy that thing?
I want some to eat hehe

Now that's what you call quality content! Short, with a proper demo and in understandable human language. Thank you!
My teacher had to spend over 2 lessons explaining this and I still did not understand until I saw this. God bless you.
oh yeah!!!!
god bless you too
I learned more in UA-cam than School .
Your English shows everything 😎
@@onthewayofdream6826 why buddy 😂 ?
@@onthewayofdream6826 shut up...it doesn't mean that if he don't know english don't know anything
@@relianceindia3636 correct sentence should be "I learnt (past tense of learn is learnt not learned) more in youtube than I learnt in school", not " I learnt more in youtube than school"
as you are comparing what you learnt in youtube to school which doesn't make sense, you should compare what you learnt in youtube to what u learnt in school. I am not master of English and maybe even I might have made mistakes but I think I am not wrong here.
@@onthewayofdream6826 instead of teasing people that they made mistakes why not correct and teach them something?
Read the topic in 12th but could not get it the first time, seeing the real life working and application makes it easier to understand. Thank-you sir.
UA-cam recommended it now and l am B.Tech. First year student, very useful.
praise one who made all human minds
As a JEE aspirant, I thank you
unemployment awaits you.
@@soumya9734 ya I would probably sell momos after JEE
Myself JEE aspirant as well.
Listen pieces of shits. Enough is enough. The momo thing I said was just a sarcasm. Now stop fighting and raging of such shits. Get some pussy on the face and do your own job there is no meaning in correcting someone else's English when ur own life is dead. I want to be engineer and that's it after that I sell momos or your mom idc. You stay happy with your English and entrepreneurship skills or wherever you are at. But I am sure u are not at a better place than IIT coz u are doing keyboard war at a ridiculous youtube comment.
@Joe- Biden go to some banks..any bank...you will find people from iits working as clerks there....don't worry wait till you graduate..studying engineering in 2021 is useless.
I was studying TIR from an app not even searched in UA-cam that I want demonstration but it recommends I m amazed 😳 beautiful coincidence ❤️
The demo at 0:56 is using a piece of acrylic, I believe.
Yep , it's a solid pmma tube(acrilyc)

Sir ,you are spreading creativity. From India
well not from India , but okay...
Important to know: for (digital) data transportation, the thinner the cable, the more data can be transported. This is due to the spread of the signal since parts of the beam are reflected at different locations, which have a different path-length over the total cable length.
This is totally awesome 😉 I love to see physics practical experiments. Keep it up👍👍

*UA-cam recommending me this 1 day before my class 10 preboards physics exam🙂
angle of incidence is greater than critical angle.
amazing video

You forgot😒 to say the name of the person Narinder Singh Kapany👨🔬 who discovered🔬the fiber-optic cable
Who cares
Nice examples, exactly this, I was looking for.
Thankuu sir 🤗u explained very well
From India 🇮🇳
UA-cam is the best learning platform I guess
BRILLIANTLY demonstrated & explained !! Thanks Dr Boyd 😁👍🏻👍🏻
I think practical study is better than studying with books !We r just mugging up the things rather than understanding them 🙏🏼
Well actually these things doesn't described in school due to lack of material , and apparatus . But the same illustration is conducted in first year of your engineering college except iiit and medical. But if you are from like rich school then it is illustrated
You should thank to Narendra Singh Kapany - "Father of Optical Fibre", the Indian Scientist 🇮🇳 who invented this.💐💐
Yeah this is what I was trying to find in this comment section.

I got an exam in this tomorrow, how the hell did UA-cam know
It is another subject brotherr
Yesterday i just thought how to walk and today i was recommended its tutorial 🙂
How did it go?

As a student I can say that at schools we are just taught with formula and nothing else.
Hey, how many of u Kno w, that Total Internal Reflection was found by India arourd thousand years before this theory given
By Shri Shri Swami Aryabhatta
One who find value of Roots and zero, and it would make u amaze, if u know concept of doing TIR based on KOHINOOR, Lost Diamond of India, which was stolen by Britain, and still present on crown of Queen of Britain, means India Rule on Head of Britain😂
🤠ok
Hmmm👍
Even optical fiber was invented by an Indian.
@Prophet Xi Jinρing [PBUH] your name😂😂😂
👍
I wish at my school time the internet was as common as today so i could have learnt better.
Me too ..
Ever since an Indian took over as a CEO of Google, they been spinning the story that Kapany invented fiber-optic. Kapany's only contribution was to repeat the experiment of Bram Van Heel from the year before of transmitting light through a bundle of glass tubes. Transmission of light through isolated glass tubes been done since the 1800s. The real inventors and pioneers were Curtiss who developed the rod-tube system of two types of glass with a different index of refraction, and Peter Shmidt who achieved a breakthrough and developed the modern manufacturing process of vaporized glass attaching to the tube through adhesion rather than insertion thus forming a rod.
Thank you so much...now I understood how does an optical fibre work .. thank you ..
hope..all indian technical colleges will have such little practicals while during theory classes.....as we all know what practicals classes we are provided even in practical periods......today.
Thissss isssss ssssso AWESOME
I am in 10th. And UA-cam recommended me this. UA-cam is getting smarter 🔥🔥
Just studied it 8 hours ago and it has helped me
I can't go without subscribing this channel
01:30
When lights acts like water
Now this is progress
UA-cam recommend me at end of my 12th right after 2 years !!
Yeah cheers !!
The best way of teaching ... Thank you sir ♥️
Thanks for demonstration 👍🏻
Ohhh ...India's, specially JEE aspirants here ... I see😗
It's not true 😅
Literally
Class 10th students are also here
I don't think it's *total* internal reflection, because some of the light is passing through and reaching our eyes.
Thank you for posting this explanation / demonstration, it is very helpful.
If only I had a professor like him....
If total internal reflection is phenomena in which 💯 of light is reflected internally without any loss of light, how did we see the path of the light, since we know we need light to bounce to our eyes to see objects....
Awesome,Its in my study course but till now I have not seen any good example of its application with my own eyes but things have changed!!
Literally came here to understand a line from Code Geass lmao
What was the line if you may?
What line?
What line
What line jacob
The earliest reply asking for the line was sent 4 months after I'd finished the entire series. I do not remember the line, but it was earlier on if that helps.
this explanation is amazinggggg
Well, I got this in recommendation two years ago and now... But my understanding towards it has changed
I am so lucky to have that vidio on my end of the 12 class 😂😂
youtube recommending this to me right after i fucked up my physics exam confirms that there's someone spying on me
Truth! We see you doing that in your room! Kkkkkk is a joke!
Recommended after 4 years.. Thanks UA-cam
Finally I got some awesome stuffs in physics
If it is totally internally reflected why we are seeing that light..
It is called total internal because light bends inside that fibre before coming out ,, and we can see the light because the object is transparent!!!!
@harsh patel bruh at least knw the basics to light
Good question. Don't listen to morons. It's not exactly totally internally reflected when you see it. Basically not all the light rays are at angle to be totally reflected. Some do get refracted and come out so we see them. We call it total internal reflection because that is the phenomena it is based on. Like you see with the round one in second case. You don't see any light near to the source. That is the case of total internal relfection for most light rays. As for people telling you to learn basics. They either did not understand why you asked specific question or are dumb enough to not understand that something sounding simple may not be simple after all.
@@abhinayjayswal407 Even if the object is trsnsparent. If the light would have been totally internally reflected we would not have seen the light. It would have simply transmitted out the other end. As to why we can se the light is because some light rays got totally internal reflected while others refracted and came out.
I think he was asking if light get reflected totally how can we see the light path in the tube since no light is coming out. And i think it is becuse some amount ight also get refracted.
I will get more information here then all my lecture
Thank you sir, you are great ...you deserve a lot more subscribers
youtube recommended me this video after my physics online class in which sir taught this topic
This is something which i never understood in my school bcoz no one demonstrated there..! & here i got it just in 2:20 mins..!
If the internal reflection was Total, then the cable would Not have the color of the light inside. Because some of the light is escaping, you can see the color of the light on the sides of the cable.
Nice video, incredible way to explain with examples!
That lamp would be a great showpiece
WHY UA-cam WHY... WHY RECOMMEND THIS RIGHT AFTER MY PHYSICS EXAM
Does the type of light matter? For example, would a laser work? If not, why not? Colored light? What sets the signal rate and strength? That is, what device and/or process sets and/or creates the signal sent into the fiber? A form of digital pulsation of light? And, what material or materials can the cable be made of? What is most used? Plastic, nylon, flexible Plexiglas, Digital acrylic, Polycarbonate, polypropylene,etc?
See you after it reaches million of views 🙋♂️
UA-cam recommended me just at the right time after studying this and i don't even see physics stuff but still youtube got to know. Nice job youtube!
UA-cam recommended me after finishing my science pre board
Why it is necessary to incident the beam at certain angle can't we send it straight.... Why TIR??
ok.
mitochondria is the powerhouse oof cell.
sOMETHING DIFFERENt
Bruh😒
@@kirayoshikage1000 😂
How many of you didn't search for this??
Rainbow is also due to internal reflection through droplets

I m watching this in my first year university doing my Level 3 in business and economic but still curious about physics concepts.
Physics is magic
It it's total internal reflection, why can i see the light passing through? Why can i see it from the sides
Tq sir it is nice. How v can use it in diagnosis n how v can see the image of diagnised organ. Can u show tz in 3d
Thank you
Thanks,it's a good idea
why are you still able to see the light coming out along the guides? shouldn`t it all to only come out from the ends?
what i cant understand is how does it transfer all this data from just a light interaction really genius people!
Thank you sir.
It's amazing....
very beautifully present optic fiber application😍
The father of optical fiber is an Indian American scientist narender singh kapani.. Who was an Indian.
Most people haven't heard of him, but the father of fibre optics was Narinder Singh Kapany! en.m.wikipedia.org/wiki/Narinder_Singh_Kapany
Thanks for sharing your knowledge!
All the best for tomorrow's physics exam 😀😂
Thank you sir really helped me to visualize optical cable..
Excellent demonstration sir thanks a lot
I'd be interested to know what the speaker's definition of "total" is, because it doesn't seem to match up with the rest of the world. If the internal reflections are truly "total," then no light would escape from the sides. We see light escaping from the sides...
Love 😍 from India 🇮🇳
