Unformatted text preview: time T 1 = Τ + τ = (1+29 29 = 1/ But the Professor knows that their clock has slowed down, so he calculates that it arrives at their time T , where T = 1ω 2 / χ 2 Τ 1 = 12 / 2 1/ = 1+ / 1/ so T = 1/ 1+ / Alternatively, one could view this as a relativistic (receding) Doppler shift problem: Suppose Professor emits signal periodically with time T His frequency would be f = 1/T If spaceship receives signal with period T (their time), frequency received by spaceship would be ′ f = 1 T = f 1v / c 1+ v / c = 1 T 1v / c 1+ v / c so T = T 1v / c 1+ v / c...
