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.

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

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?

@@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.

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.

@robertjandegraaf5557 3 года назад

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.

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?
