The spread out portion of a compression wave is called a rarefaction. In a compression wave, the particles are compressed together in the compression phase and spread out in the rarefaction phase.
The spread-apart portion of a compressional wave is called a rarefaction. In a compressional wave, particles are pushed together (compression) and then spread apart (rarefaction) as the wave passes through a medium.
Rarefaction is the less dense part of a compression wave where the particles are spread apart.
The compressed portion of a sound wave is called the compression phase. This is where air particles are squeezed together, resulting in higher pressure and increased molecular density. The compression phase is followed by the rarefaction phase, where the air particles spread out, resulting in lower pressure and decreased molecular density.
The particles that spread farther apart after the compression of a wave passing through air are called rarefactions. These regions of lower particle density are a result of the alternating compression and expansion of air particles as the wave travels through the medium.
The opposite of a compression wave is a rarefaction wave. In a compression wave, particles are close together, whereas in a rarefaction wave, particles are spread out.

I believe you are referring to rarefaction. The "trough" of a compression / rarefaction wave is called rarefaction.
Compression is the part of a longitudinal wave where the particles of the medium are crowded together. Rarefaction is the part where the particles are spread apart.
When the particles of a medium displaces due to compression and rarefaction in the direction of the force, it is known as longitudinal waves.
Wavelength
The distance from one compression to the next compression in a longitudinal wave is called the wavelength. This distance is often used to measure the size of the wave and determine its frequency.
In a longitudinal wave, a pulse is typically referred to as a compression or a rarefaction. A compression is an area of high pressure where the particles are closely packed together, while a rarefaction is an area of low pressure where the particles are more spread out.
