Hello, thanks for reading this. I need help trying to find a way to calculate the time dilation due to gravity, from a satellite 50,000km above the surface of the Earth, traveling 10,000km/h relative to a stationary observer on Earth. A signal is being sent from the satellite to the observer, the frequency of the signal is 1.7 gigahertz (1.7E9 Hz).. Now i calculated the change in frequency due to gravitational blueshift through the conservation of energy formula, but i dont know how to continue from there and turn the change in frequency to time dilation. Any help is much appreciated! I would love to see the step by step calculations if you do decide to help, thank you!
