The speed of radio waves that your antenna registers compared to the speed of those waves that your friend’s antenna is registering, if you and your friend listen to music on the same radio station which is 100 miles to the west of you, while imagining that you are living in a universe where the speed of light is 50 m/s , and you are sitting on a train moving west at a speed of 20 m/s relative to the track while your friend moves on a train in the opposite direction at a speed of 15 m/s .

Time dilation, Length contraction and Relativistic velocity-addition Time dilation is the phenomenon predicted by the theory of special relativity that says time in two inertial reference frames moving with respect to each other will appear to be different. In particular, the time intervals on a speeding rocket will appear to be longer to you than to Ato the people on the ship (figure 1). It is expressed in the formula At = Figure 1 Light Observer Sample problem for time dilation The Hypersonic Technology Vehicle 2 (HTV-2) is an experimental rocket vehicle capable of traveling at 21,000 km/h (5830 m/s). If an electronic clock in the HTV-2 measures a time interval of exactly 1-s duration, what would observers on Earth measure the time interval to be? Special relativity also tells you that lengths get contracted at high speeds. The object is actually contracted in length as seen from the stationary reference time frame. Length contraction can be calculated using the equation L=Lo1- where…
