Resumo: In the General Theory of Relativity, gravitational force is seen as a deformation of space-time. For instance, a massless test particle in motion on a certain space-time with no forces acting on it follows a trajectory called a null geodesic. Recently, the Event Horizon Telescope showed the first image of a shadow of the supermassive black hole M87*. A black hole shadow is formed by null geodesics. As a consequence, the understanding of null geodesics of black holes is crucial for explaining the nature of such black holes. A package for computing Bound Time-like geodesics about a Kerr Black Hole has been developed and is publicly available in the Black Hole perturbation toolkit We intend to contribute to this package by coming up with a code for computing Null geodesics about a Kerr and a Schwarzschild black hole. We have developed the code based on the article
