But in optical fibre both the mediums are air only and there is just a thin layer of plastic so how can we say that light travels from any optically denser to an optically rarer medium in this case
@Abhir Bansal optical fibre consists of 2 parts-core and cladding.the core being denser and the cladding(outer covering) being rarer therefore TIR can occur for incident angles greater than the critical angle..
It should had been " the refraction happen when the incident angle of dense material and its normal surface vector is less than 45 degree and total reflection when that angle greater than 45 degree"
Great Explaination... I really need a video in topic of Application of Total internal reflection.
It's great u teach everything in only 7 min 😍🤩 wonderful explaination thank you mam
Everything means....did she explained any other class 12 physics imp. topic in 7 min. Plz do answer
ماشاءاللہ آواز ہے آپ کی❣️💖And Explanation is also too good
Good explanation! Keep it up!
This was really fascinating to watch
Really nice vid who is here in 2022?
In diamond the incident ray is not traveling from denser medium?
Please make subtitles.available
Its fantastic the way she explained
n easy to get understand n really
appreciated that teaching method
Thankz for clarifying my doubts
🌹💐💐✌️✌️🤗
Such a clear expalnation, im just looking for this thankyou mam, love from 🙂🇮🇳
How lovely voice!! Thank you so much☆☆☆

Nice and charming explanation
This is inssane but y suns are so less according to me this channel should have atleast 17million subscribers ❤️🔥🔥🔥🔥🔥🔥🔥😎😎❤️
true
Wow thank u so much! I understood mam!❤
Wonderful explanation. 💓
I like it
One of the best visual explanation of this topic......Student will never use to forgot this topic after watching this vedio 👍👍👍👍

Great going

It was really helpful!!!thank you 😊
Good explanation ✨️
Very Good
Mashallah Ma'am, superb voice and thanks for your help by this superb video
Who's here from 10th 2024!
Super explained
Yesss...
Nice video .do watch it. it will help
It was gr8....but what is a critical angle??
The angle of incident when the angle of refraction is equal to 90 degree
@@afifhamimi7258 well said
The angle of incidence for which the angle of refraction is equal to 90° is called critical angle
It is very helpful 👍
Optical fibre what??? Cube or cable?😅
Thank you mam🙏
Wonderful explanation
You said
Super explanation madam
Thx ma'am 🙂
Thank you ❤️
Thank you so much..!😍
Best one 🛐
Very well explained, thanks!
Thank you
Amazing
