This is the second in a series of papers whose purpose is to investigate the possible strength of a cosmic background of gravitational radiation. In this paper we present a metric which may be used to describe exact plane gravitational waves propagating over a homogeneous background spacetime, and we find solutions representing waves of linear polarization over backgrounds of Bianchi types I, III, V, and VI, as well as over a background with a smooth global inhomogeneity. In all of these cases, we find the property that inhomogeneity in the structure of the initial cosmic singularity evolves into gravitational waves propagating over a homogeneous background spacetime.
