In the graphic representation of a sound wave, pressure variations are typically depicted by fluctuations of the curve above and below the average pressure value, similar to density variations.
How does the representation of pressure in a sound wave differ from that of density?

In a sound wave, the representation of pressure typically mirrors density variations. Both pressure and density exhibit fluctuations above and below average values as the wave propagates. However, in graphical representations, pressure variations are directly correlated with changes in density, showcasing the alternating compressions (high pressure, high density) and rarefactions (low pressure, low density) within the wave.
