Measuring the speed of sound, illustration. A woman creates a sharp, loud sound. The sound wave bounces off the wall and returns as an echo. An observer records the time between the sound and its echo. The distance travelled from the origin of the sound to the wall, and back to the observer, divided by the time taken, will give the speed of sound. The speed of sound in air is 340 metres per second. | |
