Question

Differentiate between Rarefaction and compression in two points​

Answer 1

Answer:

❋ 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.
