Instead of crests and troughs, longitudinal waves have compressions and rarefactions. Compression. A compression is a region in a longitudinal wave where the particles are closest together. Rarefaction. A rarefaction is a region in a longitudinal wave where the particles are furthest apart.

compression is that part of the longitudinal wave in which the particles of the medium are closer to one another.

rarefaction is that part of the longitudinal wave in which the particles of the medium are farther apart from one another....
