Question

Quizplus · Accepted Answer

Sound waves are physical vibrations that propagate through a medium, typically air. They are characterized by changes in air pressure over time, creating compressions and rarefactions that our ears can detect. Therefore, option C is the best choice. The other options describe parts of the ear that respond to sound waves, but not the waves themselves.
