We calculate the time dilation ratio at altitude h and divide this by the time dilation calculated at the surface of the earth take the square root of the result and then multiply this calculated ratio by the time interval at the surface of the earth and the result of the calculation is the amount of time that has passed on the faster clock located higher in the field at altitude h. T t 0 1-v 2 c 2 12. Delta t Dt refers to the two-position time or observer time in seconds.
The time measured when observer and event are in the same gravitational potential and t f is the time as measured when at an infinite distance from any mass.
The time between ticks and tocks is again given by the distance traveled by the red pulse divided by c. Combine the two equations above. As that path is straight the distance is shorter and as the speed of light is supposed to be constant the time taken should be different than the amount of time taken for the ball to cover the path we see. In this equation t 0 is the proper time for an event ie.
