- Abstract
The analogy between optics and mechanics not only provides a cohesive framework to understand particle motion in mechanics and light propagation in geometrical optics, but it also extends to the intricate realm of general relativity, especially when considering static metrics. Recent scholarly publications have fortified the notion that such an analogy is remarkably applicable to general relativity's complex scenarios. In the research presented in this paper, we delve into the material medium approach, which allows us to deduce the refractive index correlated with the gravitational field emanating from a compact celestial object endowed with a quadrupole moment. Exploring within the confines of this approach, we scrutinize the influence of the quadrupole parameter on the frequency modulation of photons, adhering strictly to the relativistic approximation parameters. This scrutiny leads us to a deeper investigation of the renowned redshift phenomenon, a pivotal concept in the general theory of relativity. Furthermore, leveraging the calculated refractive index, we probe into the nuances of radar echo delay, conscientiously accounting for the quadrupole moment's impact. The findings may offer insights that could potentially be useful in further theoretical investigations of GR.
