2. An observer S sees a flash of red light 1200 m from his position and a flash of blue light straight line. He measures the time interval between 720 m closer to him and on the same the occurrences of the flashes to be 5 microseconds, the red flash occurring first. a. What is the relative velocity v of a second observer S' who would record these flashes as occurring at the same place? b. From the point of...

Observer O sees a red flash of light at the origin at t = 0 and a blue flash of light at x = 3.19 km at a time t = 7.56 μs. What are the distance and the time interval between the flashes according to observer O', who moves relative to O in the direction of increasing x with a speed of 0.630c? Assume that the origins of the two coordinate systems line up at t = t' =...

Please help me understand this problem
An observer in an inertial reference frame S sees lightning strike simultaneously at two points that are 870 nm apart. He measures that the location of the first lightning strike is given by the four coordinates x1 0 m, y1 0 m, z1 0 m, and t0 s. He measures that the location of the second lightning strike is given by the four coordinates X2 = 870 m, y2 = 0 m, z2 0...

Alice G LOO Bob Let's revisit the simultaneity problem from worksheet 11. To make things concrete, we'll include specific numbers. Bob is standing on the ground watching Alice go by in a high-speed train. As seen in Bob's reference frame, Alice is traveling to the right at speed v = +0.80c. As measured in Bob's frame, Alice's rail car is 12 m long. Alice is sitting in the exact center of the train car. At the instant that the Alice...
