#### Sound WavesEdit

Sound is a longitudinal compression-expansion wave through matter. The wave speed is

- (2.11)

where and are constants and is the *absolute temperature*. The absolute temperature is measured in Kelvins and is numerically given by

- (2.12)

where is the temperature in Celsius degrees. The angular frequency of sound waves is thus given by

- (2.13)

The speed of sound in air at normal temperatures is about .
