17 meters ke pass Sound echo toh nahin karega lekin reverb toh karega na? Kyunki Rock ek achha material hai jo echo produce karta hai.

[@abbasaliir1910]

@khanacademyindia Sir how to measure distance with the help os sound

[@selenophile413]

Yrr ye bol kon rha h so swwweeeeeet voice ❤

[@santoshtiwari6199]

Sir which software are u using plz tell 👯us My humble request🙏😊

U are great man great Salam hai tumko

[@pratikpanda8932]

Umm excuse me sir, could you please tell me how to concentrate. I love physics and maths from childhood. I also love reading variety of books on cosmology. But now a days i have lost my concentration so much that a single clap sound can disturb me from my books. Could you please help me sir. Thank You

[@prahladsingh5107]

Mere sath bhi yahi hai bahi

[@SpiceCabinetReloaded]

@@prahladsingh5107 same here

[@SpiceCabinetReloaded]

i think it is all because you have lost all your interest from those subjects and you are reading them for only knowledge you should read them for fun and should apply whatever you read . i too resolved my problem with this method and i too love reading them but instead of just reading i try to apply them in my daily life so that i dont lose my interest

[@profullakumardas4111]

Me too

Thanku so much sir... 🎩 😁 👕👍Great! 👖

[@santoshtiwari6199]

Blah blah blah

[@vinodsuthar3755]

Sir ji sound speed in air 332M h kya

[@worldofmusic1058]

Vai mai bhi soch raha tha

[@R.A.SPATHAN]

❤❤❤❤

[@Abbashabi]

brother than why we listen echo of speaker

[@GurvinderSingh-rv7sy]

Sir please can you tell me why do you multiply 0.1sec both sides

[@Divya-sq3kv]

"d" ki value nikalne k liye bro Sorry i'm 4 months late

[@yogolu]

Nice video sir

[@unagaraju5721]

Saund to har jaga ja takrata he to kayi jan sakeg ki kitnedurmehe

[@Artsfashionboy233]

But the exact distance is 17.2 m for echo

[@harishsapate23]

I have a doubt sir .... At 22°c the speed of sound is 344 m/s .... So if we calculate then the minimum distance will be 17.2 meters that is given in our textbook .... But my teacher says that if the distance between source of sound and obstacle is more than 17.2 meters then we cannot hear the echo .... I told her that if the distance is more than 17.2 meters then also we can hear echol but she said that it is wrong .... We can only hear echo if the distance is exactly 17.2 meters .... Please tell me how can I explain her

[@bhatadha9255]

She's dumb or what? Simply say that's a minimum criteria not the maximum

[@utkarshgamer7205]

To hear the sound distinctly (clearly) then the minimum distance between reflecting surface in air should be at a minimum distance of approximately 17metere

[@kantilab]

Dear sir, sound k frequency kabhi khatam hotahai? One particular sound...

[@gentleman2283]

Time ke saath disturbance jis ki wajah se sound produce huwa uski kinetic energy conserve khatm hojati phir frequency zero hojati hai

[@ankitchoudhary5862]

Sir sound to sb jageh reflect hoti h to hamesha echo kyu nhi hota h

[@ABDxLM]

Because our ear cannot hear if sound reflect back in less than 0.1 sec

[@HARDY5911]

Haji mulla bismillah lula gula silall lula sulia hanmola ❤

[@shivanipariharsmallt3006]

Speed ki 340m/s ye value fix ha kya

[@riyangaming5092]

Nope

[@vinodsuthar3755]

👍👍👍👌👌👌

[@shinchanbhardeaj1765]

Super saiyan

[@mithunpradhan5970]

New home me eco sunaideti hai kiun

[@ukd2028]

Kyoki wahan pr koi aisa saman nhi hota jo aap ke sound ko absorb kre aur isliye aapki awaj aapko reflect ho ke sunai pdti h. But wo eco nhi reverbation(गूंजना) hai. Eco tb hogi jb room 17m lamba ho

[@hashiransari7253]

Vegita

[@shinchanbhardeaj1765]

Vegeta

[@azad8842]
