For example, sound travels fastest through solids, followed by liquids and then gases. The speed of sound is determined by the medium through which it travels. As a result, the sound’s speed increases as the temperature rises.You might be interested: Where Do Seismic Waves Travel Slowest And Fastest? Temperature of the medium: The frequency of the sound waves and the temperature of the medium is strictly proportional. As a result, the sound’s speed increases as the density of the medium increases. Whenever the medium is thick, the molecules are tightly packed, allowing sound to travel further. Two factors that influence sound’s speed:ĭensity of the medium: Sound waves require a medium to travel, and the density of the medium is thought to be one of the influences upon which the sound’s speed depends. As a result, sound waves don’t really travel through a vacuum, or their speed is zero. A sound wave is a longitudinal wave which requires a medium to travel.
