Write any three difference between compression and rarefaction
Answers
Explanation:
A compression is a region in a longitudinal wave where the particles are closest together. A rarefaction is a region in a longitudinal wave where the particles are furthest apart. ... The region where the medium is compressed is known as a compression and the region where the medium is spread out is known as a rarefaction.
❋ Compression :-
➠ It is the portion of the medium in which density increases when longitudinal wave travels.
➠ In the compression there is temporary decrease in volume of the medium and increase in density.
➠ The distance between the particles in the compression is less than the normal distance. The centre of compression is the position of maximum pleasure and maximum density.
❋ Rarefactions :-
➠ It is the position of the medium in which density decreases when longitudinal wave travels.
➠ In the refraction, there is temporary increase in volume of the medium and decrease in density.
➠ The distance between the particles in the rare fraction is greater than the normal distance.
➠ The centre of refraction is a position of minimum temperature and minimum density.
