In the context of general relativity and the study of spacetime, a null tetrad is a mathematical construct used to facilitate the analysis of light rays and the behavior of null (light-like) geodesics. A null tetrad consists of four vectors, typically denoted as \\( l^\\mu, n^\\mu, m^\\mu, \\) and \\( \\bar\{m\}^\\mu \\), which satisfy certain orthogonality and normalization conditions.
