Gravitational waves (GWs) are novel signals that probe the behavior of gravity in both the strong and weak-field regimes. As these waves propagate towards us over cosmological distance, they are sensitive to the presence of inhomogeneities in the Universe. Similarly to light, GWs can be lensed by intervening galaxies or clusters of galaxies, and lead to multiple magnified and delayed images from the same source. One important difference with light though is that the detection of GWs is sensitive to the phase of the wave, which can change from emission to detection due to strong lensing. In this talk I will explain what this change of phase is, how it can affect future observations, and how it can be used as a unique effect that will help identify GW lensed events.
