Q. 23.8( 4 Votes )

Can you hear your own words if you are standing in a perfect vacuum? Can you hear your friend in the same conditions?

Answer :

When we speak the vocal cords in our throat vibrate. These vibrations reach our ears internally. So even in a perfect vacuum, we can hear our own words. But in the same conditions, we cannot hear our friend due to the absence of a medium which allows propagating the vibrations from one point to the other.
