Sound Waves[edit]

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

c = ( \gamma R T_{abs} )^{1/2} (2.11)

where \gamma and R are constants and T_{abs} is the absolute temperature. The absolute temperature is measured in Kelvins and is numerically given by

T_{abs} = T_C + 273.16^{\circ} (2.12)

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

 \omega = ck = ( \gamma R T_{abs} )^{1/2} k . (2.13)

The speed of sound in air at normal temperatures is about 340 \mbox{ m} \mbox{ s}^{-1}.
