The first direct detection of gravitational waves (GW) opens the new era of gravitational wave astronomy. The strongly lensed GWs seen by 3G detectors accompanied by electromagnetic (EM) signals could be used to test modified theories of gravity, serve as a milestone in precision cosmology, and apply to studying dark matter distributions. I will introduce the event rate observed by 3G detectors as well as those applications of lensed GW-EM system to fundamental physics and cosmology.
