Physics – Sound Wave Speed March 21, 2006 Sound Wave Speed If the speed at which sound waves traveled depended on frequency how would that change the way we perceive the world? At this time the speed of a sound wave, created by a pressure disturbance traveling through a medium, is determined by the time it takes the wave to travel a specific distance (www.physicsclassroom.com). Frequency refers to the number of vibrations an individual particle makes per unit of time, whereas speed refers to the distance the disturbance travels per unit of time. Knowing that the speed of light travels faster than sound, humans can observe a detectable time delay between the thunder and lightning during a storm. The time delay between the arrival of the light wave (lightning) and the arrival of the sound wave (thunder) allows a person to approximate his/her distance from the storm location. Another advantage to understanding the perception of time delays between two events is the phenomenon of echolocation. If you have ever made a holler within a canyon, perhaps you have heard an echo of your
