Solution
The correct option is C Pressure
When a sound wave travels through a medium, say air, the particles of the medium get disturbed in the same fashion, i.e. compression and rarefaction. When air particles come closer it is called compression. On the other hand, when particles go farther than their normal position it is called rarefaction. When compression takes place in the medium, the density and pressure of the medium increase. When rarefaction takes place in the medium, density, and pressure of the medium decrease. This increase and decrease in density and pressure are temporary.
