Sound 06: Application of ultrasound CBSE Class IX Science Physics

[@ArzmuhammadMaitlo-l1f]

This is the best lecturer and conceptual

[@k.g.s.aruldhinakar2576]

There is clarity and good quality in the teaching. Thanks.

[@_frozenclub]

Aap bhout bhout acche se ppdhate ho. Sidhe hi samajh as gya . Thank you so much ❤️

[@triptykumari9858]

Very nice and Thanks mam and make a next video of extra knowledge of physics

[@Mayank__pareek]

Watch the video at 1.75x

[@zahirkhan6197]

Very clear explanation .

[@simrankhangura3951]

Where is echo ? Reverberations? Its uses ? These r most important topics...

[@DevrajBeniwal]

Echo may be heard more than more once due to successive or multiply reflections

[@DevrajBeniwal]

The repeated reflection that results in this persistence of sound is called reverberation

[@indiansinger5979]

Amazing way

[@rupaligawade231]

Thank you mam Very nice explanation

[@anuprabhakarkera5553]

Iron bhi toh solid object hai na fir use kuch obstacle ki kya zarurat hai reflect hone keliye??

[@anuprabhakarkera5553]

Pls koi batao

Thanx mam and you very beauti full

Jaise ultra sonic wave sonar me Reflection of sound Transmitter to receiver distance =2d Kya room me echo sound ka distance hmara aawaz hamari Kano tk wapas aane me time 0.1 second Lagta h kya wo distance = 2d Ke according calculated hai d=distance between wall to source

[@rajeshojha1941]

Mam verrrrrrrrrrrrrrrrrrrrrrrrrrry nice explanation

[@rajthakre7016]

Mam plz explain how bats use ultrasonic waves to catch it's prey..

[@alokdwivedistudent2235]

Very very nice

[@RahulKumar-qx5xf]

Mam sach me aapne unacedmy ko fell kar diya

[@sahilkumar-zd7fq]

Echo sound propagation sunne Ke liye 34.4 meter distance Velocity of sound = 344m/s in air Time taken to receive our echo sound is t=0.1second Total distance covered of our echo sounds from our mouth source to my ear observer is = 34.4 x 2 = 68.8 meter To kya time 0.1 second ye fix value h Weather temperature change pe sound ki velocity increase hoti h Us time echo distance 34.4 meter hoga ya change hoga

[@patelpiyushkumarmangaldas8825]

Maybe change hoga

[@daitarinisank4272]

No

[@daitarinisank4272]

Echo sound ko sunne ke liye 17.2 disance hona zaruri hai to 17.2*2 =32.4m

[@daitarinisank4272]

Kya

[@k.darshan5896]

thanks madam jiii

[@ranisinha218]

Radar in not here why ?

[@selfiequeen7940]

Echo and reverberation m confusion h plz explain kijia

[@shristikushwaha6063]

Repeated reflection of sound called echo nd multiple reflection of sound called reverberation

[@patelpiyushkumarmangaldas8825]

2d=vxt equation samjh mein nahi aaye will plz explain in detail

[@anuprabhakarkera5553]

2d isliye liya hai kyuki ultrs sonic wave source se object aur object se source tak travel hota hai na toh 2distance aagayana

[@krishnapradhan4564]

Thanks

[@LolAntic]

Fully explanation nahi hai Kuch samajh nahi aaya

[@lokeshbiradar9570]

Nice mam

[@shriprakashpandey1796]

Better

[@mdistakhar5506]

Echo kiya ha mam please explain it

[@rishavtiwary9741]

Bouncing back of sound after striking a surface is known as echo

[@piyushdubey194]

Nice
