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

[@madhurawarghade312]

[@ritumakhija7513]

[@pinkykukreja4588]

[@NamanKashyapRajput]

Because the vacuum in the not air and any particles to the help of the sound to travel .

[@manojmiddepogu1711]

Sound needs air to travel
But space is a vaccum

[@AviSaxena-k9d]

20 to 20000

[@jyothiduppla5466]

Human beings can here from 20Hz to 20,000Hz or 20kHz only few animals can here below and above Human beings

[@Horridhenry015_we]

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

[@HarpreetSingh-sc6lg]

Because air present nahi hoti Manu Bahia

[@pandayji6177]

Because in space there is no air medium

[@RudraTanwar0049RT]

Kyoki sound ka median chahiye hota hai

[@Artistpanther316]

[@_Aditya_Ghadge_]

Bhai Money lagta he ap screenshot le sakte ho

[@_Aditya_Ghadge_]

​@@Priyanjali_vlogyes true

[@bhola9560]

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

[@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

[@anshrai1413]

❤ kafi acha explanation karte ho

[@MukeshKumar-vc9uz]

INFRA SOUND CAN BE HEARD BY DOG AISO

[@pokebuddy1101]

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

[@anmolvikramtude]

Sound needs a medium to propagate or travel
If you agree then like

[@AnandBariha-pr9hp]

That sound need a medium(air,solid,liquid)but in the vacume no medium we dos not hear sound

[@artistic_anabia_]

Because there is no air in space..

[@SunilMeena-zz3hl]

wuwwuwuwssaxwi

[@R.V-gaming_777]

Because there is no medium to travel sound

[@hackgamer5062]

No we can because this is no median to travel wave

[@dakshdulaw]

Sir, sound needs a medium to propagate there are no free particles in a vacuum which will cause no vibration. No vibration = No sound. I think this is the answer.

[@Mukeshgupta-mz3zl]

Static ,rolling,sliding,fluid,air

[@HitanshRajPurseth]

There are no particles present for vibration to take place

[@CRIME-GAMERZ5790]

No , because space sound in travel not air

[@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

[@AnitaKuthari]

Sound cannot travel in space because space we need air

[@sudeepbarua9619]

Gas se bhi sound produce hoti hai
