It is called a compression.
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.
According to my textbook it says rarefaction, is the less dense region of a longitudinal wave
A longitudinal wave can go through solids, liquids, and gases.A transversal wave will usually only go through solids. (Electromagnetic waves, however, can also go through empty space.)
Microwaves are part of the electromagnetic spectrum and are transverse waves in that the displacement is perpendicular to the direction of travel.
The metal part of a pencil is called a ferrule.
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.
Just had this lesson this afternoon, 06.23.2009. Longitudinal/compressional waves were drawn as a spring. The rarefaction is drawn as the expanded part of the spring and the compression as the compressed part.
RAREFRACTION
Filum terminale or terminal thread is a fragile fibrous tissue strand which is the longitudinal support of the spinal cord. Its upper part is called filum terminale internum and the lower part called filum terminale externum.

Assuming that you are referring to longitudinal waves, the area where particles are closest together would be called the "compression" area. The "rarefaction" is the opposite; this is where the medium is least dense. Sound is a good example of longitudinal waves. If you look closely at a speaker cone, you be able to see that they seem to move in and out very rapidly. This is what "pushes" and "pulls" the air molecules and creates compressions and rarefactions which our ears receive and transmit as a neural impulse to our brain, allowing us to hear. Although transverse and longitudinal waves are both different types of waves, they are dissimilar (particles in a transverse wave move perpendicular to the motion of the wave (up and down) where as particles in a longitudinal wave move in the direction the wave is traveling).

A transverse wave. The other sort are called longitudinal waves - a compressed part of whatever medium it is followed by a decompressed part.
