A spacecraft (reference frame S') moves past Earth
Chapter 36, Problem 36.75(choose chapter or problem)
A spacecraft (reference frame S') moves past Earth (referenceframe S) at velocity v, which points along the x andx' axes. The spacecraft emits a light beam (speed c) alongits y' axis as shown in Fig. 36-17. (a) What angle 0 doesthis light beam make withthe x axis in the Earthsreference frame? (b) Usevelocity transformations toshow that the light moveswith speed c also in theEarths reference frame,(c) Compare these relativisticresults to what you wouldhave obtained classically(Galilean transformations).FIGURE 36-17 75.
