Sound waves can indeed travel through air. Unlike electromagnetic waves, which can propagate through a vacuum, sound waves require a medium to travel. In most cases, air acts as the medium for sound waves, although they can also travel through other substances like liquids and solids.
When a sound is produced, it causes the particles in the medium (such as air molecules) to vibrate in a pattern of compressions and rarefactions. These vibrations create a mechanical disturbance that propagates through the medium as a sound wave. As the sound wave travels, it transfers energy from one particle to the next, allowing the sound to propagate.
However, it's important to note that the speed of sound and the characteristics of sound waves can vary depending on the medium through which they travel. For example, sound travels faster in solids than in liquids, and faster in liquids than in gases like air.
