An inertial frame $K^{\prime }$ moves with a constant speed $v$ with respect to another inertial frame $K$ along their common $x$ -direction. Let $(x,ct)$ and $\left(x^{\prime },c{t}^{\prime }\right)$ denote the spacetime coordinates in the frames $K$ and $K^{\prime }$, respectively. Which of the following spacetime diagrams correctly describes the $t^{\prime }$ - axis ($x^{\prime }=0$ line) and the $x^{\prime }$ - axis ($t^{\prime }=0$ line) in the $x$ -ct plane? (In the following figures $tan\varphi =v/c$)
