Over the past years\, electromagne tic and gravitational observations have been used to understand the nature of black holes and the material around them. Our ability to learn about t he underlying physics\, however\, depends heavily on our understanding of the gravity theory that describes the geometry around these compact object s\, and for the electromagnetic observations\, also on the complex astroph ysics that produces the observed radiation. In this talk\, I will discuss our current ability to constrain and detect deviations from general relati vity using (i) the electromagnetic radiation emitted by an accretion disk around a black hole\, and (ii) the gravitational waves produced when compa rable-mass black holes \;collide\, and when a small compact object fal ls into a supermassive one in an extreme mass-ratio inspiral. I will also compare the constraining capabilities of these two types of observations t o show how current gravitational wave observations have already placed con straints on possible modifications to general relativity\, that are more s tringent than what can be achieved with current and near-future electromag netic observations.
