The Other Frame is moving in the $+x$ direction with $x$-velocity $\beta=0.25$ with respect to the Home Frame. The two-observer space time diagram in figure R5.9 shows the diagram $t$ and $x$ axes of the Home Frame and the diagram $t^{\prime}$ axis of the Other Frame. Which of the choices in that Figure best corresponds to the diagram $x^{\prime}$ axis?

Question

The $x^{\prime}$ axis should make the same angle with the $x$ axis as the $t^{\prime}$ axis makes with the $t$ axis.

The Other Frame Is Moving in The +x+x+x Direction With xxx -Velocity β=0.25\beta=0.25β=0.25

The Other Frame Is Moving in The $+x$ Direction With $x$ -Velocity $\beta=0.25$
