Sound waves are mechanical waves, longitudinal waves, and pressure waves: Mechanical waves: Sound waves require a medium, such as a solid, liquid, or gas, to travel through. Longitudinal waves: Sound waves include compressions and rarefactions as they travel through a medium. Compressions occur when particles move closer together, creating areas of high pressure. The particles of the medium vibrate in the same direction as the wave's propagation. Pressure waves: Sound waves are also called pressure waves. The pitch of a sound depends on the frequency of the sound wave. A high frequency sound wave has a high pitch, and a low frequency sound wave has a low pitch. /louder @db3045
