expression of time after n wave.
wave). Alice then waves to Bob simultane- ously (as measured by her) with Bob's wave. Bob then waves to Alice simultaneously (as measured by him) with Alice's second wave. And so on. What are the readings on Alice's watch for all the times she waves? And like- wise for Bob? A rocket flies between two planets that are one light-year apart. What should the rocket's speed be so that the time elapsed on the cap- tain's watch is one year? .23. A passing train* A train with length 15 cs moves at speed 3c/5. (1 cs is one “light-second.” It equals (1)(3 • 108 m/s)(1 s) = 3 · 108 m.) How much time does it take to pass a person standing on the ground, as measured by that person? Solve this by working in the frame of the person, and then again by working in the frame of the train. _.24. Simultaneous waves* Alice flies past Bob at speed v. Right when she passes, they both set their watches to zero. When Alice's watch shows a time T, she waves to Bob. Bob then waves to Alice simul- taneously (as measured by him) with Alice's wave (so this is before he actually sees her
2.28. Simultaneous waves again** Solve Exercise 1.24 by using a Minkowski dia- gram from the point of view of an observer who sees Alice and Bob moving with equal and opposite speeds.
