Drawing the sound wave
The crests indicate regions of high pressure and the troughs, low pressure.
The variations in pressure can be measured as the wave moves past a stationary object.

When a sound wave is drawn, it usually resembles an ocean wave with crests (peaks) and troughs (valleys).
The crests indicate regions of high pressure and the troughs, low pressure. The variations in pressure can be measured as the wave moves past a stationary object. |
