First, consider the barometric formula which gives the density (or pressure) of air at a height h above the surface of Earth. We assume complete equilibrium, mechanical, and thermal. The argument is illustrated in Fig. 2.1.1.

You can observe direct evidence of the speed of sound while watching a fireworks display. The flash of an explosion is seen well before its sound is heard, implying both that sound travels at a finite speed and that it is much slower than light. You can also directly sense the frequency of a sound. Perception of frequency is called pitch.

(Hint: Compare the speed of sound in water and air in the table.) Can you calculate the speed of sound in air and the wave speed on the string in the Violin simulation below? The product of the wavelength and frequency can be used to determine the speed of sound in air and wave speed on the violin string: The speed of sound is the distance that sound waves travel in a given amount of time.

Because the speed of sound depends on the density of the material, and the density depends on the temperature, there is a relationship between the temperature in a given medium and the speed of sound in the medium.

In a fluid, because the absence of shear forces, sound waves are longitudinal. A solid can support both longitudinal and transverse sound waves. The speed of sound is the same for all frequencies and wavelengths of sound in air.
