Abstract: The gravitational polarizability properties of black holes are compared andcontrasted with their electromagnetic polarizability properties. The -shape- or-height- multipolar Love numbers h l of a black hole are defined and computed.They are then compared to their electromagnetic analogs h l^{EM}. The Lovenumbers h l give the height of the l-th multipolar -tidal bulge- raised on thehorizon of a black hole by faraway masses. We also discuss the shape of thetidal bulge raised by a test mass m, in the limit where m gets very close tothe horizon.
