1.3.2 Exercise: Spacetime Intervals A Let event A be the emission of a pulse of light from a laser beam on the earth. Let event B be that pulse bouncing off a mirror on the moon. Let event C be that reflected pulse returning to a detector 10 m away from the laser. Let event D be the laser emitting a second pulse at the same time (in the laboratory frame) as the first pulse is received by the detector. Specify the category of the interval between events A and B: A and C: A and D: B and C: C and D:
