The density and pressure variations in the graphic representation of a sound wave illustrate how these properties change with distance as the wave propagates through the medium, showcasing the compressions and rarefactions within the wave.
Can you describe how the density and pressure variations relate to the movement of a sound wave in the medium?

Density and pressure variations in a sound wave depict fluctuations above and below average values as the wave travels through a medium. Compressions, where density and pressure are high, are represented by peaks, while rarefactions, with low pressure and spread-out particles, are depicted by troughs. These variations illustrate the oscillatory movement of the wave’s energy through the medium.
