Because of the longitudinal motion of the air particles, there are regions in the air where the air particles are
compressed together (Compressions) and other regions where the air particles are spread apart (Rarefactions).

Sound requires something to vibrate. In a perfect vacuum,
there is nothing to vibrate and no sound wave can be produced.

Echolocation is performed by certain animals to locate food or obstacles in darkness, such as in caves and in the ocean.
Bats and Dolphins produce sounds and then listen for echoes. The delay between the emission of a sound and the arrival of an echo
indicates the distance of an object.

CompressionRarefaction
At one end of this tube is a speaker. As sound waves pass through the tube, an area of compression will push a taller flame, while an area of rarefaction will have a shorter flame, or possibly no flame at all.
