3 A spaceship (A) is moving at speed c/2 with respect to another spaceship (B). Observers in A and B set their clocks so that an event at (x, y, z, t) of a photon arriving has coordinates (0, 0, 0, 0) in A and also (0, 0, 0, 0) in B. A second photon arrives at (x = 1.00 m, 0, 0, 0 s) in the frame of ship A. (a) Find the coordinates and time of the second photon arriving as seen by an observer in frame B. (b) In which frame are the two events simultaneous and in which frame are they are not simultaneous
