Question

WHA ARE THE PROPER DEFINITIONS OF COMPRESSIONS AND RAREFACTION WITH EXAMPLES

Answer 1

Answer:

Because of the longitudinal motion of the air particles, there are regions in the air where the air particles are compressed together and other regions where the air particles are spread apart. These regions are known as compressions and rarefactions respectively.

Explanation:

If the prong of a tuning fork vibrates in the air, for example, the layer of air adjacent to the prong undergoes compression when the prong moves so as to squeeze the air molecules together. When the prong springs back in the opposite direction, however, it leaves an area of reduced air pressure. This is rarefaction.Sep
