[@harshvardhanupadhyay12345]

2:21 Because sound needs a medium of propagation. It travels the fastest in solids and slowest in air . Vacuum means that there is no air , so without any medium of propagation we can't hear any sound

[@Shilpa256]

2:20 because sound need medium to travel,in our life sound is travel with solid, liquid and gas. In vacuum there is no things need for sound to vibrate

[@KhushbuuUpadhyay]

12:34 we cannot hear sound in space because sound need a medium to propogate and in space there is no air molecule are present and only air is a medium for sound so we can't hear sound in space

[@Lakshay-l9u]

18:28 Pigeons can hear the lowest frequencies of 1 Hz. This helps them in navigation. 18:45 Noctuid moths can hear the highest frequencies of 240,000 Hz. This helps them in escaping from bats.

No because there is no air, liquid, solid in space and sound needs a medium for propagation that's why we can't hear sounds in space.

[@lilabenpatel408]

2:21 Because sound needs a medium and air is the best medium for sound

[@Cutiepienandu]

we can not hear sound in the space because in the space there has no solid,liquid and gas

[@ShivamKumar-cg7io]

6:40 my exam tommorow thanks bhaiyaa

[@bsb_vlogs_Delhi]

Because sound needs a medium to travel which is air if there is no air sound will be not able to travel from one place to another

[@AmritaSingh-d4k7r]

Kyuki vha koi medium nhi hota jis se sound travel kar sake 2:17

[@Bagheer108]

Sir because sound need mediam to travel and in vacuum have no mediam Jay shree mahakal ❤❤❤

[@manojmiddepogu1711]

Sound needs air to travel But space is a vaccum

[@Memes-TOBI]

18:34 dogs can hear infrasonic sound

[@YadavJi-xb5qb]

2:25 because in space there is no medium so that sound could travel

[@KdeviSMPKKumari-rv3vz]

Thank you sir for explain this chapter you are very best teacher for me🙏🙏

[@rituomer3013]

Aisa isliye kyuki jab vaccum create hota hai to usme matter ke molecules ( air ke molecules nahi hote ) jis karan sound wahan molecules ko vibrate kar ke sound produce nahi kar sakta ...

[@yoyohoney7102]

We cannot hear sounds in space as you already said that there is no air means it is vaccum and no sound can travel in vaccum as it needs a medium for its propogation . 😊

[@Captain_141dth]

Sound cannot travel in vaccum because sounds move by vibrating molecules and in vaccum there is no molecules so sound cannot move in vaccum

[@universeofgaming6558]

Ans 20 to 20000 hz Hz is the measuring of frequency

[@pyarelal7613]

Because in air vaccum is present

[@MohdNafis-vy8pt]

sound need medium ( air solid liquid) in vacuum no molecules

[@RudraTanwar0049RT]

Kyoki sound ka median chahiye hota hai

[@LalitaKhatri-so1bm]

There is no atmosphere in space. So sound cannnot travel in space .

[@seemashrivas191]

[@Artistpanther316]

Kyunki jab ham Tali maarte Hain to sirf vibration hoti hai aur vah hawa ke dwara hamare kanon mein jaati hai hamara dimag ek awaaz produce karta hai because air is important

[@bhola9560]

Because sound needs a form to travel like solid , liquid and gas

[@AliveLegend_XD]

sound cant be heard in vacuum as it needs a medium for travelling

[@neerajbhadoria4977]

Yaya

[@Muskan-cx]

Sound need a medium like air but in space there is is no air so it means there is no air molecules in space and if there no molecules in space so vibration cannot travel that is why we can not listen any sound in space

[@kmgamer2981]

Sound is traveling in gas

Gas se bhi sound produce hoti hai

[@kituurajmeena4808]

because sound need to meadium for travel and air is meadium and in vaccum air is not present so sound can not travel in vaccum

[@tanuvarshney9781]

Because sound is travel through air molecule

[@sunitaswami7721]

20 hz to 20000 hz

[@ritumakhija7513]

20 Hz to 20000Hz(20kHz)

[@navtaj_brar]

Sir we can not hear sound in space because space is a vacuum and sound does not travels in vacuum.

[@pokebuddy1101]

Because the vacuum is not a air so it divert the sound

[@hackgamer5062]

No we can because this is no median to travel wave

[@editsbyrohitraj]

There is no air present in vacuum

[@Horridhenry015_we]

Because sound is produced due to vibration of molecules and in vacuum there is no molecule

[@RajhansYadav-i9f]

Because there are not air 2:20

[@Otaku_lite]

Hha ha got u

[@gulabchandgupta5731]

Because Sound travels with the help of medium which air .Thus sound Cannot travel in vaccum
