Abstract
Gravitational shock waves of ordern=2 are considered and their description in radiation coordinates is discussed. It is found that in such coordinates there exist necessarily (trivial) discontinuities of first derivatives ofg μv . The structure of the propagation relation for this form of the shock wave is derived and the discontinuities of the Newman-Penrose field variables are determined.
