Total Internal Reflection Demo: Optical Fibers
HTML-код
- Опубликовано: 19 авг 2016
- 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.
RUclips 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 👍
❤️❤️❤️❤️❤️ruclips.net/video/K7Z5-NJc9qs/видео.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

Guess what bitch I'm on data so I make your point completely invalid because it doesn't adhere to my conditions hahajahaha
@@karenamma7716 crap damn got me good 😅
@@justinlipkin but well the data travels intercontinentally through fiber optic so ye
Human mind is totally awesome!
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
@@devanshpatel3465 😄😅
Human mind is awesome until unless they're using it for destruction
Now that's what you call quality content! Short, with a proper demo and in understandable human language. Thank you!

FYI Optical fibre is invented by an Indian-American Narinder Singh Kapany .
@@ss_somu ok
@@ss_somu No, it's the work of many scientists

I learned more in RUclips 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?
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
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.
BRILLIANTLY demonstrated & explained !! Thanks Dr Boyd 😁👍🏻👍🏻
The demo at 0:56 is using a piece of acrylic, I believe.
Yep , it's a solid pmma tube(acrilyc)

omygod the light reached your profile pic 😱
I was studying TIR from an app not even searched in RUclips that I want demonstration but it recommends I m amazed 😳 beautiful coincidence ❤️
This is totally awesome 😉 I love to see physics practical experiments. Keep it up👍👍
Nice examples, exactly this, I was looking for.
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.
Thank you for posting this explanation / demonstration, it is very helpful.
Nice video, incredible way to explain with examples!
The best way of teaching ... Thank you sir ♥️
angle of incidence is greater than critical angle.
amazing video
Great Informative and Interesting video is this .
tHANK YOU SIR .
As a student I can say that at schools we are just taught with formula and nothing else.
RUclips recommended it now and l am B.Tech. First year student, very useful.
Thank you so much...now I understood how does an optical fibre work .. thank you ..
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.
Thanks for demonstration 👍🏻
this explanation is amazinggggg
Thank you sir, you are great ...you deserve a lot more subscribers
Just studied it 8 hours ago and it has helped me
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!!
No one :
*RUclips recommending me this 1 day before my class 10 preboards physics exam🙂
I can't go without subscribing this channel
Thanks for sharing your knowledge!
Excellent demonstration sir thanks a lot
RUclips recommend me at end of my 12th right after 2 years !!
Yeah cheers !!
This is so good, fresh.
Sir ,you are spreading creativity. From India
well not from India , but okay...
You explained it very nicely...
As a physics enthusiast , I loved your video
Thank you sir really helped me to visualize optical cable..
شكرا جدا والله حضرتك سهلت عليا دراسة الفيزياء 👏
praise one who made all human minds
Thissss isssss ssssso AWESOME
Thank you sir.
It's amazing....
very beautifully present optic fiber application😍
Superb explanation.
Thankuu sir 🤗u explained very well
From India 🇮🇳
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
thanks for your help
Thanks,it's a good idea
best explanation ... thanks sir
RUclips is the best learning platform I guess
Best demonstration man ...❤️👍
I wish at my school time the internet was as common as today so i could have learnt better.
Me too ..
If only I had a professor like him....
Thanks, you are amazing
nice demonstrations sir.
Very nice explanation thank you very much sir'
Good info, informative for all
👍👍
RUclips 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!
You continously inspire me
Thanks for the demonstration sir very much usefull😇
Very helpful. Thanks
Beautiful fact.
You forgot😒 to say the name of the person Narinder Singh Kapany👨🔬 who discovered🔬the fiber-optic cable
Who cares
Thank you!!!
thanks for the lesson
I got an exam in this tomorrow, how the hell did RUclips know
It is another subject brotherr
Yesterday i just thought how to walk and today i was recommended its tutorial 🙂
How did it go?
@@alyssafisher2902 I got a pretty good score actually, thanks for asking
Nice :)
Thank you
Could fiber optics be used to create a passive radiant cooling system where the redirected light energy (IR) could be used to heat water or whatever else at a distance without losing a significant power?
Well, I got this in recommendation two years ago and now... But my understanding towards it has changed
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?
thank you teacher...

When lights acts like water
Now this is progress
Very nice explanation 😀😀
He explained really good
Nice demo
thanks Sir for this nic video
Thnk u so much Sir! very easy to understand 😁

As we can see, there are many angles in which successful internal reflection taking place. Doesn't it mean that there is not a particular angle on which it happens?
thk for this demo
That lamp would be a great showpiece
Thank you sir ❤❤❤❤.
Nice explanation
just awesome
Recommended after 4 years.. Thanks RUclips
Finally I got some awesome stuffs in physics
Nice video...i was lokking it....now i have a lot exoeriance about it
Amazing!
I m watching this in my first year university doing my Level 3 in business and economic but still curious about physics concepts.
is there any perfect material that transmit 100% without losing amplitude. clearly fiber walls are emitting some photons?
Thanks for video
Fabulous sir
Sir,
Is there any difference between OFC used for network connectivity(Single Mode) and Lighting Decoration(as on your table)
It was going to be very difficult to understand the concept but, thanks to you.
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....
If it is getting totally reflected how are we able to see the same through the glass tube?
Why can I still see a glow throughout the length of the tube as if some of the light is escaping before it gets to the end
Thank you sir
I don't think it's *total* internal reflection, because some of the light is passing through and reaching our eyes.
