Question

Compression is the region of low pressure.

• A. True
• B. False

Answer 1

The correct option is B

False

Because of the longitudinal motion of the air molecules, there are regions in the air where the molecules are compressed together and other regions where they are spread apart. These regions are known as compressions and rarefactions respectively. The compressions are regions of high air pressure whereas the rarefactions are regions of low air pressure.
