(c) State what is meant by the term "Proper time interval". (d) Time Dilation associated with Special Relativity causes the atomic clocks onboard GPS satellites to run slow relative to Earth bound clocks. Given an average altitude above the Earth's surface of 20, 180km use the expression d7 = dt??1 – 2 to determine the time discrepancy between Earth and Satellite clocks over the course of a day. Approximately what error in positional accuracy or distance measurement would result from this?
Expert Answer
Proper time is just the distance travelled by an object in spacetime. It is obtained by plotting the position against time. The path is called as world line. The length of this path is called spacetime interval or proper time(for the observer moving
