53. (a) The spatial separation between the two bursts is vt . We project this length onto the direction perpendicular to the light rays headed to Earth and obtain D app = vt sin θ . (b) Burst 1 is emitted a time t ahead of burst 2. Also, burst 1 has to travel an extra distance L more than burst 2 before reaching the Earth, where L = vt cos θ (see Fig. 38-22); this requires an
