The Properties of Sound Waves Video Tutorial describes the various properties of sound and relates such properties to waves and to our perceptions of sound. Numerous examples, illustrations, and animations assist in the explanations.
Dec 28, 2020 · Sound is a type of mechanical wave or an oscillation of matter. When a sound wave propagates through a medium, such as air, it does so by causing the air molecules to vibrate, which causes changes in air pressure. The speed of sound in air is around 343 m/s but can vary with temperature.
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 \(\PageIndex{2}\)).
Here we examine what makes sound special among waves, and how we can employ the tools of general weave mechanics to this particular wave phenomenon.
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.
