Question

Is sound travel in a vacuum?

Answer 1

Sound travel in a vacuum: A sound is a type of energy that results from an object's or body's vibration. Sound travels through air particles and needs a medium to go through.

1. The vacuum, as we all know, is an empty space devoid of all stuff. It's a place where the gaseous pressure is significantly lower than the atmospheric pressure.
2. Sound is a mechanical wave and requires a medium to travel.
3. In a vacuum, sound cannot travel because there are no molecules that can vibrate or convey the wave.

Hence, sound cannot travel in a vacuum.
