Answer 1

$\huge\bf{Hey\:mate\:here's\:ur\:ans}$

A longitudinal wave travels through a medium in the form of compressions and rarefactions.

________________________________________

$\underline{Compression}$ :->
A compression is a region of the medium in which particles are compressed i.e. particles come closer. The distance between the particles becomes less than the normal distance between them.

_________________________________________

$\underline{Rarefaction}$ :->

A rarefaction is a region of the medium in which particles are rarefied i.e. particles get farther apart. The distance between the particles becomes mate than the normal distance between them.

_________________________________________

The distance between two consecutive compressions or two consecutive rarefactions is called vas wavelength of the wave.

Answer 2

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.
