Physics · Special Theory of Relativity
A π0 meson at rest decays into two photons moving along the x-axis. They are both detected simultaneously after a time t = 10 s in the rest frame. In an inertial frame moving with a velocity v = 0.8c in the direction of one of the photons, the absolute value of the time interval between the two detections is:
