It needs a material medium for propagation
light can travel through a vacuum whereas sound cant
sound can't travel through a vacuum. or a place without air.
there is no air in a vaccum. and sound needs air for the sound waves to travel through.
Sound can travel on the moon because there is no atmosphere. Space is a vacuum that does not allow sound to travel.
Sound (and vibration) are a wave system of sequential compressions and rarefactions of a material. These waves are mechanical and do need a substance through which to travel. They cannot travel through a vacuum.
Sound needs something to travel through. That's usually air on Earth. Space is a vacuum - therefore, sound cannot travel through it.
Why cant sound travel through empty space
There is no air for sound to travel through.
no the only waves that can go through space is the electromagnetic waves and it doesnt need sound or matter to travel.compressional waves have to come off of something and travel{like sound} it cant travel because there is nothing to travel through.the vacuum of space is just nothing and only light can go through as well, but it takes time.
sound cant travel on an asteroid because it has no atmosphere. it could travel through it.
Because there is no atmosphere in space, therefore nothing can carry the sound waves of your vocal cords. Sound relies on pressure waves moving through air. Therefore, in the absolute vacuum of space, no sound can be heard at all.
light can but sound cant as there is no air
