Question

what happens during a rarefaction of a sound wave? the particles that a sound wave passes through are spread out. the particles that a sound wave passes through are annihilated. the particles that a sound wave passes through are pressed together.

Explanation:

Sound waves are longitudinal waves. In a rarefaction of a sound - wave, the particles of the medium through which the sound is traveling spread out. Particle annihilation is not a part of sound - wave behavior, and particles being pressed together is compression, not rarefaction.

Answer:

The particles that a sound wave passes through are spread out.
