Abstract
A non-perturbative model of a gravitational wave with pure radiation in an anisotropic Bianchi universe of type IV is constructed. A relationship between the space-time metric parameters and those of the pure radiation is obtained. The trajectories of light rays are found as a solution to the eikonal equation in a given metric. The parameters of light signal propagation in a gravitational wave are calculated. The delay relation for radiation in a gravitational wave is obtained.
