Because gravitational and electromagnetic fields are coupled in the presence of a charged black hole, such a black hole possesses a cross section for the conversion of gravitational to electromagnetic radiation and vice versa. In this paper, this phenomenon is used to consider the conversion scattering of a ''test charge'' (which is modeled as small mass, charged black hole) in a classical gravitational or electromagnetic radiation field. The total cross section for the conversion between these types of radiation is numerically calculated to be sigma/sub totconv/ = 1.33e/sup 2/. Differential cross sections for incident plane or circularly polarized radiation are also exhibited. (AIP)
