For a particular cosmic model, the wavelength of the cosmic density (CD) wave is estimated to be 0.516 Mpc just prior to the recombination. A series of peaks, or periodicity, is predicted by the theory to appear in the redshift distribution of objects affected by the CD wave, the z value corresponding to each peak satisfying the relation ln(1+z)=0.205 n+B, where n is an integer and B is the phase constant. The theory interprets the z(em) distribution of the observed quasars as a vestige of the CD wave. Further estimates are given for the coherence length of the CD wave train, and the maximum scale of the observable inhomogeneities in the large scale distribution of galaxies and the other observable vestige of the CD wave which appears in the z(ab) distribution of the absorption redshift systems of quasars. Observations are in agreement with theoretical predictions.
