Special Relativity-Space and Time Section 15.7, The Twin-Trip, compares the times experienced by a traveling twin and a stay-at- home twin. The 2-hour trip experienced by the traveling twin is observed to take 2.5 hours from a frame of reference on earth, as evidenced by the sending and receiving of regularly-spaced flashes of light. The 6-minute-interval flashes emitted by the spaceship are seen from earth at 12-minute intervals when the spaceship is leaving the earth, and at 3-minute intervals when the spaceship is approaching the earth. Read the textbook carefully and fill in the readings on the spaceship clock below for each flash emitted, and on the earth clock for each flash received.
