Chapter 37, Problem 20P

GO As in Fig. 37-9, reference frame S' passes reference frame S with a certain velocity. Events 1 and 2 are to have a certain temporal separation ∆t' according to the S' observer. However, their spatial separation ∆x' according to that observer has not been set yet. Figure 37- 24 gives their temporal separation ∆t according to the S observer as a function of ∆x' for a range of ∆x' values. The vertical axis scale is set by ∆t_a = 6.00 µs. What is ∆t'?
