Watch a suspended vibrating spring to learn about the propagation of sound waves — sound Learn about the propagation of sound waves from a point source by observing the motion of a suspended vibrating spring.

In physics, the speed at which sound waves propagate through a medium depends on its physical properties, such as temperature and density.12

For dry air at a temperature of 0 °C (32 °F), the modern value for the speed of sound is 331.29 metres (1,086.9 feet) per second.12

Because sound behaves as a longitudinal wave in gases, its velocity is determined by the gas laws and is primarily dependent on the absolute temperature of the medium rather than the ambient pressure.2
