Which of the following statements is true? sound waves create areas of high and low pressure. areas of high pressure are called compressions. areas of low pressure are called rarefactions. all of the above.

All of the above

Explanation:

Sound waves are mechanical waves consisting of the oscillations of the particles in a medium. They are longitudinal waves, which means that the vibrations of the particles occur in a direction parallel to the direction of propagation of the wave.

This type of wave consists of alternating regions where:

- the density of the particles is higher: these regions are called compressions, and they correspond to high pressure regions

- the density of the particles is lower: these regions are called rarefactions, and they correspond to low pressure regions
