Understanding Sound Waves
Variations in air pressure create sound through compressions and rarefactions caused by vibrating objects, such as tuning forks and vocal cords. Sound travels at approximately 340 meters per second in air, but its speed is influenced by temperature rather than air pressure. Interestingly, while higher altitudes have lower pressure, it’s the colder temperatures that slow down sound, not the density of air molecules.In this clip
