Sound velocity refers to the speed at which sound waves travel through a medium, such as air, water, or solids. This speed varies depending on factors like temperature, pressure, and the medium's density. In general, sound travels faster in liquids and solids than in gases due to the closer arrangement of particles. In air at room temperature, the sound velocity is approximately 343 meters per second. In water, it increases to about 1,480 meters per second, while in steel, it can reach around 5,960 meters per second. Understanding sound velocity is essential in fields like acoustics and engineering.
