Stopping Light for 60 Seconds Urdu Hindi 

Agar crystal ki length maloom hoti tuo bohot acha hota. We are very thankful to Takhti channel. Urdu zuban mein itna scientific channel ye aik hi hoga.

Dr sahab ap bht atcha Kam kr rhy han. Warna hum to apny ird gird logon ko peer faqeer aur jinn bhot he discuss krty sunty han

پلیز آپ سولر پینل فوٹان اور اسکی پراپرٹیز اور قدرت کی چار بنیادی فورسز پہ بھی ویڈیو بنائیں؟؟،

Welldone Sir ap ka samjhane ka style bohat acha ha. Please ek video photonic computer or quantum computer k fark pa banaim

Masha Allah Excellent explanation..

Great sir thanx for teach us

Sir please make thumnail in English so that we all can read and understand. As you know most of the people understand Urdu but cannot read. Generally your viewers can read English. Thanks

Aap aur student ? Aap to professor k v baap lgte ho ? Kaun padhata he aap ko, sir ?☺ ... aisa lgtahe k mano aap biswa ke har harkat ko baarikisey dekhtey ho,, wah kya mulayam hai aap ki prakashvangi(explaination style)/andaaz

I love it .this is my childhood questions.

Total internal reflection is used in optical fibers and also in endoscope, telecomunication etc.

Will this quantum storage system of light may replace optical fiber cable system ????? And also light differs its frequency when being used in quantum system ????

Sir AGR rupidium ka Jo cloud ha his ma light slow ho jati ha AGR uski shape round krda tyre type aur uski boundaries PR mirror place krda then put light in so light mehfoooz hoskti ha

ncie video sir

Sir you are a great teacher

Sir I have a question here. Jab ap light ko is material mai preserve kartay hain to kya hamain is material k andar light travel karti nazar aye gi?

Awesome sir

sir agar ek aesa cub banaya jaye jisme glass use ho us per light photons chor diye jaye or light ek glass se dosre glass per reflect ho circle ki tarha tou kia ye continue aese reflect hoti rahegi ?

You are amazing

Nice sir

اجعلها أسهل واحكم

Bohot khub

اس سے تو یہ ثابت ہوا کہ روشنی وہاں رکی نہیں بلکہ متحرک رہی اور راستہ ملتے ہی وہاں سے نکل گئی ۔ بات روشنی کو روکے رکھنے کی ھے ۔ تو اگر کسی بوکس میں مختلف اینگلز پر کئی آئینے رکھیں جائیں جن میں اگر ایک آئینے پر روشنی پڑے تو اسے دوسرے آئینے ٹرانسفر کردیا جائے اور یہ تمام ائینے اس ایک دوسرے کو ٹرانسفر کرتے رہیں تو پھر روشنی کبھی بھی خود سے باہر نہیں نکل سکتی ۔ اور اس طرح اس سے کئی کام لئے جاسکیں گے ۔

sir. light ka speed constant nahi raha. aisa kyon hai

Sir 1 question hwever not regarding to this video but still grip my mindSir, Is Demon have weight/mass when it divert itself to a human being? As we all know that Demons are created from fire and fire have no weight... Plz I am curious to 9 about it

Sir peltier effect k bary mn video bna den plz plz ....

Good

Great

Kya aap scientist ho ? Sir plz kahiye

Einstein theory se sabit hua hai k speed of light constant rhti hai to phir us ki theory to ghalt sabit hui Yahan to speed of light ko control kr ke kam ky ja rha hai

Then how can we say that speed of light is constant in all the references? As we know that in any medium whose refractive index is greater than 1 , light bends toward the normal to maintain its constant velocity( i.e. C) by reducing its size of path. And also if it got trap in any medium like yitrium then is it not violating the theories of relativity? Answer to ur question : T.I.R is widely used in optical fibers for telecommunication and it has various applications in designing sensors like sensor for rain detection on car wind shield used in TATA Aria car etc.

I don't know because I had listened this first.

Assalamualikum mujhe ye toh nhi pata ki light ko rok sakte h ki nhi but ye zaroor pata ki jab light kisi medium se guzarti h toh uski kuch energy us medium ke under zabt ho jaati h jisse hume mehsoos hota h ki light ki speed kam ho gyi h kyunki us ki roshni mein tabdili hoti h. aur jab kisi cheez ki energy mein tabdeeli aati h tab uska matlab ye h ki uski energy kahin aur waste ho rhi h naki uski speed mein farq hota h balki uski speed wahi rehti h lekin mujhe ye bhi pata h ki jo jitna speed se travel karta h uski energy bhi utni hi zyada hoti h. so that's why kuch kaha nahi jaa sakta jab tak is baare mein poori research na kar lun. dua karo ye experiment kisi musalman ke naam hi likha jaaye

Optical fiber is already transmitting data

👌👌❤️❤️❤️

sir unified feild theory ...plzzz....sir

Einstein ne to prove kiya thaaa ki speed of light her frame of eeferance me constant hogi

Sir i think... light hamesha r har cheez me store ho jati hai.. jis ki waja sy black color wajood me aya... Q k ap dekhen jab light kisi bhi cheez sy takra k hamari ankhon me parrti hai jis ki waja sy hamen us ki maujoodgi ya us k wajood ka ehsas hota hai... ham us cheez ko observe krty hain hamen light ko store ni balky get karny pr dhian dena chahiy k black color sy light get kesy karni hai... why SKY is black or think about black hole...why we call it black hole... i think All sky is bright but because wo hamen black tab hi nazr ata hai q k light hamari Eyes me nhi phnch pati... it is big challenge for scientists to do this... Sir the concept of Total internal reflection is Wrong because ... agr diamond bright hota hai to saf zahir hai k us me light disperse ho k bahir nikal rahi hai jo k ham observe karty hain... Sir I was read a topic "black body radiations" jis me black body me light obsorb ho jati hai... so Ye kehna ghalat na ho ga k jahan black color hai wahan roshni ziada hoti hai... its my view about light and darkness... right or wrong i don't know because i am student... sorry for ur response time...

Insaan nahi kuchh special insaan ye sab kaam kar rahay hain 98% including me ye sab dekh ker mun khulay ke'khulay reh jaa te hain.

pher to light ta speed vi constant nehi hain

Photon high standerd

Bhai apko sugar hai check karao

Apney kbhi kisi Indian ko nahi dekha hoga k wo apni video k title MN Urdu likhey lkn hum Pakistani shyd marjaengey agr unki zaban culture ko promote nhi krengey ...
