What Is Sound?: How Does Sound Travel?

The video explains that sound must travel through a medium and is produced by vibrations. Sound travels in waves of energy, specifically as longitudinal waves where particles vibrate in the direction of the wave. These waves transmit sound through vibrations and collisions in matter, whether solid, liquid, or gas. Sound propagates in all directions from its source, allowing everyone nearby to hear it.
