Question

differentiate between compression and rarefaction on the basis of density in sound wave​

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 increase in density.

: The distance between the particles in the compression is less than normal distance. The centre of compression is the position of maximum pleasure and maximum density.

* Rare fraction ..

: 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 maximum density.
