Question

What is rarefaction ? AG a sound wave toquelo through ais, the region in which air is not at low pressure and low density is called rarefaction.​

Answer 1

Answer:

• Rarefaction, in the physics of sound, segment of one cycle of a longitudinal wave during its travel or motion, the other segment being compression. ... A succession of rarefactions and compressions makes up the longitudinal wave motion that emanates from an acoustic source.

Answer 2

Answer:

RAREFACTION:-

rarefaction, in the physics of sound, segment of one cycle of a longitudinal wave during its travel or motion, the other segment being compression. ... This is rarefaction. A succession of rarefactions and compressions makes up the longitudinal wave motion that emanates from an acoustic source.

Explanation:

Sound will be produced by from a vibrating source. When a particle is vibrated, it moves to and fro about a mean point. It initially pushes the medium on one side and moves back to the other side creating a space of low pressure and density. this portion of medium is called a rarefaction.
