Cannot be heard as sound being a mechanical wave badly needs a material medium
THat sound requires matter to travel to be heard. Therefore a vacuum has no matter hence no sound can be heard
No, because sound cannot travel in the vacuum.
The sound not travel through vacuum because sound need a medium to travel.
Sound cannot travel through a vacuum.
Nothing! Sound is wave and needs a medium to pass through in order to be heard !!!Nothing, because sound cannot travel in a vacuum.
It is told that sound cannot travel trough vacuum. Sound can only travel through medium.
vacuum
Space is essentially a vacuum. Sound needs a medium to travel through to be heard. Therefore the sound of a rocket engine cannot be heard in space.
sound needs a medium to travel. material medium is necessary for propogation of sound. in vaccum sound do not travel. that's the reason why we are not able to hear sound in this case. Jordi101
Space is a vacuum. Sound cannot travel in vacuum
Sound waves cannot travel in a vacuum.
Sound does not travel in a vacuum. It needs a medium in which to travel (unlike light) and so sound cannot travel in a vacuum. However, in a solid sound travels faster than in air.
