A Transverse Wave
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.
wavelength
That is a primary or compressional wave. It is called compressional because the particles move toward and away from each other. It is called a primary wave because it arrives first. Sound waves in water or air are examples of primary waves. The other type of wave is a secondary or shear wave. It is called secondary because it travels more slowly and arrives later than a primary wave. It is called a shear wave because the particles move at right angles to the direction of wave motion. The side-to-side motion of a Slinky is an example of a shear wave. The other, other type of wave is a tertiary wave, which is a channeled saound wave trapped in the SoFAR channel in the ocean. Because this is typically the third type of wave identified on seismograms, this is also known as a tertiary wave or "t-phase". Love Waves and Rayleigh waves are special cases of mixed-mode waves that travel along the surface of the Earth.
No, particles of the medium do not become part of the wave
when the particles of the medium are far apart, that part of the wave is called a?

Ok
A rarefaction., in contrast to a compression.

The point on a longitudinal wave where the particles of a medium are stretched apart.
diffraction
Rarefaction is the part of the sound wave where the air particles are the farthest apart from each other. It's like the "trough" of a transverse wave. The size of this part affects the wavelength and amplitude of the sound produced, which changes the volume and pitch. Note that there's also another part of the wave called "compression". This is like the "peak" of a transverse wave.
