The Lorentz transformation is a fundamental concept in classical electrodynamics and special relativity, describing how physical quantities change between two inertial frames moving at a constant velocity relative to each other. Consider two inertial frames, ( S ) and ( S' ), where ( S' ) moves with a velocity ( v ) along the x-axis relative to ( S ). The Lorentz transformation relates the spacetime coordinates ((t, x, y, z)) in frame ( S ) to ((t', x', y', z')) in frame ( S' ). The transformations are given by: [ t' = \gamma \left( t - \frac{v x}{c^2} \right), \quad x' = \gamma (x - vt), \quad y' = y, \quad z' = z, ] where (\gamma = \frac{1}{\sqrt{1 - \frac{v^2}{c^2}}}) is the Lorentz factor, and (c) is the
