WebA 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. The region where the medium is compressed is known as a compression and the region where the medium is spread out is known as a rarefaction. WebThe dislocation density in the “piston” increased after the shock-wave compression by a factor of 10 4 and amounted to 7.4 × 10 16 m −2. The value of micro-distortions in the crystal lattice after the explosion has increased ten times: value Δa/a to the “piston” is 0.77 × 10 −3 in the initial state and after the treatment—0.16 ...
