Sound needs a medium to travel. Suggest a reason. Can sound travel in vacuum?
Answers
No sound cannot travel in a vacuum.It needs air so that it can propagate and reach human ear by which we listen it.
Hey dude,
Sound needs a medium to travel. Suggest a reason.
❦That's because sound is a mechanical wave.
❦In contrast, electromagnetic waves require no medium, but can still travel through one.
❦Since a vacuum is defined as lacking a medium, then sound and correspondingly, mechanical waves, cannot propagate through a vacuum.
❦This is why we can't hear voices or sounds in space.
Can sound travel in Vaccum?
❦But it seems that in some circumstances, sound can jump between objects in a vacuum after all.
❦Sound waves are travelling vibrations of particles in media such as air, water or metal.
❦So it stands to reason that they cannot travel through empty space, where there are no atoms or molecules to vibrate.
