Do sound travels faster in vacuum than in air?
No. Sounds cannot travel at all in a vacuum because there are no particles to carry the sound wave.
I thin that sound requires a medium for propagation so the speed of sound in vacuum should be zero while in air it is about 332 mt/sec
speed of sound in air c = 343 m/s at 20?C ...while in vacuum its nil because there is no medium to propagate
Air, because in a vacuum, sound cannot travel
In vacuum sound cannot travel at all, as the others explained. In water however, sound travels faster than in air, because the higher density of the medium.
Where are the grammar police when you need them?
my vacuum is as loud as always can't figure out how eliminate air.
There is no sound in a vacuum
Noooo you can't hear anything in vacuum but you can in a air. A example of a vacuum is empty space. You can hardly hear even your own voice
