  7. Abstract:
  8. The discovery of gravitational waves by LIGO has undoubtedly opened a new window on our observations of the universe. In this way, valuable observational information can be obtained from near astrophysical sources to distant cosmic structures. In addition to the source of gravitational wave propagation, with the help of phenomena such as the magnification of light intensity by intermediate objects in the path of the gravitational wave to the observer, useful information can be obtained from the distribution of cosmic matter. The study of this effect is possible with the help of frequency changes per unit time. Therefore, what can be measured are the magnification effects of the distribution of cosmic matter in terms of frequencies that change with time on the amplitude of gravitational waves. In this thesis we studied these effects in the context of the standard model of cosmology
