This is how fiber optics work 👍

[@mrflowband]

In 1870, Irishman John Tyndall did exactly this experiment (using the light of a candle instead of a laser) and discovered that light could travel inside a stream of water. Tyndall's experiment made it possible for 83 years later, in 1953, the Indian physicist Narinder Singh Kapany to design and manufacture a glass cable capable of transporting light, which he later called fiber optics.

[@MadScientist267]

This isn't quite accurate lol You see the water as green because it's all scattering in the stream... That's not even close to "total"... But in an abstract way, it demonstrates the result. Sorta.

[@shubhamkumar-nw1ui]

Thank you

[@eric4946]

Yeah , looking at it I was like if you’re getting TIR you wouldn’t see the light lol This is a lot of scattering.

[@sunvetr]

If it really was 100% internal reflection then we wouldn't see the light cause it wouldn't escape the water to meet our eyes

[@Learnnhvfun]

👍

[@SgtNicholasAngle]

I was thinking the same thing

[@Kendral_999]

Not every reflection occurring in the stream is internal because of the surface imperfections, but the initial beam disappears because of 100% internal reflection.

[@andreimiga8101]

I'm pretty sure that it's because the beam itself is imperfect. A perfect laser beam cannot be seen except from its front, but we can see it from the side here.

It’s not total internal reflection if i can see the light inside the water stream. That means some photons are leaking out of the water stream.

Is it really 'total' internal reflection? Since you can still see light escape fron the stream, it doesn't totally reflect it internally... I think.

[@dcmeserve]

Should find a way to fill it more indirectly so the water is stable near the hole. If the stream is nice and steady, you’ll be able to see how the beam is bouncing back and forth within the stream.

[@MrMonkeyDLufy69]

Why didn't u directly put the laser on the bottle??

[@Albin_Evald]

Probably a lot of minor reflections out that we dont see, but pretty cool!

[@rubayethassan5615]

That's awesome maybe that's how the optical fiber works.... I love physics so much but obviously don't like to do maths to solve problems of physics....😑

[@drahcirnibot4916]

My first inclination was why did you have to reflect the laser? My assumption is that you had to reduce the power of the laser through the reflection so it can travel through the water. So I guess my next question would be will a full power laser do the same thing without reflecting it?

[@grasyavagancia5137]

Sorry for spoiling, but it not total, is it? If it was, we would not see any light in the waterstream.
