  The main objective of the present paper is to investigate the curvature
properties of generalized pp-wave metric. It is shown that generalized pp-wave
spacetime is Ricci generalized pseudosymmetric, 2-quasi-Einstein and
generalized quasi-Einstein in the sense of Chaki. As a special case it is shown
that pp-wave spacetime is semisymmetric, semisymmetric due to conformal and
projective curvature tensors, $R$-space by Venzi and satisfies the
pseudosymmetric type condition $P\cdot P = -\frac{1}{3}Q(S, P)$. Again we
investigate the sufficient condition for which a generalized pp-wave spacetime
turns into pp-wave spacetime, pure radiation spacetime, locally symmetric and
recurrent. Finally, it is shown that the energy-momentum tensor of pp-wave
spacetime is parallel if and only if it is cyclic parallel. And the energy
momentum tensor is Codazzi type if it is cyclic parallel but the converse is
not true as shown by an example. Finally we make a comparison between the
curvature properties of the Robinson-Trautman metric and generalized pp-wave
metric.
