  In this review paper we investigate the connection between gravity and
electromagnetism from Faraday to the present day. The particular focus is on
the connection between gravitational and electromagnetic radiation. We discuss
electromagnetic radiation produced when a gravitational wave passes through a
magnetic field. We then discuss the interaction of electromagnetic radiation
with gravitational waves via Feynman diagrams of the process $graviton +
graviton \to photon + photon$. Finally we review recent work on the vacuum
production of counterpart electromagnetic radiation by gravitational waves.
