Sound waves are longitudinal waves that make particles vibrate in the same direction as the wave. They can travel through solids, liquids, and gases.
After many vibrations, a series of compressions and rarefactions moves out from the speaker as a sound wave. The red graph shows the gauge pressure of the air versus the distance from the speaker. Pressures vary only slightly from atmospheric pressure for ordinary sounds.
Identify the features of a sound wave and learn about pitch, frequency, amplitude and loudness in this guide for KS3 Physics students aged 11-14 from BBC Bitesize.
The amplitude and frequency of a sound wave can be examined using a microphone and oscilloscope. By measuring the speed of sound we can apply the wave equation to determine its wavelength.
A sound wave is the pattern of disturbance caused by the energy travelling away from the source of the sound. Sound waves are longitudinal waves. This means that the propagation of vibration of particles is parallel to the energy wave propagation direction.
On the atomic scale, sound is a disturbance of atoms that is far more ordered than their thermal motions. In many instances, sound is a periodic wave, and the atoms undergo simple harmonic motion. Thus, sound waves can induce oscillations and resonance effects (Figure 17.2).
