Gravitational waves have very low frequency so it is very difficult to detect them by using any ordinary detectors and systems. For detection of gravitational waves a laser Interferometric system prepare i.e. known as LIGO. It contains combination of Michelson interferometer and  Fabry perot interferometer, which provide long path for travel laser beams between mirrors. High speed detectors used for detection of changes occurs in ripples due to effect of gravitational waves during propagation between mirrors.

Gravitational waves are most basic sense of space time changes occur in Universe. According to Einstein theory of relativity gravitational waves are generated by acceleration of massive objects in cosmos. If a star explodes as a super gravitational waves carry energy away from detonation at speed of light.  If black holes collide they cause these ripples in space time to propagate like ripples across surface of a pond. These ripples provide behavior of gravitational waves changes. These ripples can be detected by using high sensitive sensors as used in LIGO ( Laser Interferometer Gravitational-Wave Observatory ).
