Consider a fixed and a moving system with their clocks synchronized and their origins aligned at t=t'=0. (a) Draw on a spacetime diagram in the fixed system a line expressing all the events occurring at t'=0. (b) Draw on this diagram a line expressing all the events occurring at x'=0. (c) Draw all the world lines for light that pass through t=t'=0. (d) Are the x' and ct' axes perpendicular? Explain.
