Answer 1

Answer:

no it does requires medium

Answer 2

Answer:

No

Explanation:

No, sound can not use a vacuum to travel through it. Sound always need a medium to travel through them. Without any medium sound can not travel. Speed of sound is dependent on the density of the medium through which it travels. So. the sound needs a medium to travel either they are solid, liquid or gas. But vacuum does not contain any medium like solid, liquid or gas so sound can not travel through it.
