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
@@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.
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.
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.

I don't know the answers to your questions. These are just demonstrations that are in our USU physics department equipment room, maintained by James Coburn, james.coburn@usu.edu. You could write to him if you would like. You might want to give him a link to this video and tell help exactly where in the video that the equipment of interest is used.
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?
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.
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?
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....
Yes, the surface needs to be smooth so that the reflection will be specular instead of diffuse. But you don't need a reflective surface, like a mirror. All you need is to have the light ray inside a solid transparent cylinder, and total internal reflection will do the rest. For more information, see th-cam.com/video/gKaBLLjq-2I/w-d-xo.html.
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
TH-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 👍

✅
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?

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
Finally I got some awesome stuffs in physics
I don't think it's *total* internal reflection, because some of the light is passing through and reaching our eyes.
Why it is necessary to incident the beam at certain angle can't we send it straight.... Why TIR??
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.
Nice video, incredible way to explain with examples!

very beautifully present optic fiber application😍
TH-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!
Why no close-up of the black coil?
Why was the the last coil on the table black? How does light go thru black plastic?
Only the outside of the black cable is black. It is transparent on the inside, and that's where the light goes.
That lamp would be a great showpiece
This is so good, fresh.

This is something which i never understood in my school bcoz no one demonstrated there..! & here i got it just in 2:20 mins..!
Thank you sir really helped me to visualize optical cable..
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.
You explained it very nicely...
Thanks for sharing your knowledge!
Thanks,it's a good idea

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?
Very nice explanation 😀😀
It it's total internal reflection, why can i see the light passing through? Why can i see it from the sides
Thanks, you are amazing

What happens is you use two light source, one on each end, similar to the flat plastic surface used in this demonstration?
Very helpful. Thanks
*CBSE* students after hearing Total internal reflection : *RAINBOW* 😂
but what you realy need is a pollished side surface right? to the light beam will bounce?
Yes, the surface needs to be smooth so that the reflection will be specular instead of diffuse. But you don't need a reflective surface, like a mirror. All you need is to have the light ray inside a solid transparent cylinder, and total internal reflection will do the rest. For more information, see th-cam.com/video/gKaBLLjq-2I/w-d-xo.html.
