I don't know how to do this problem...can any1 please help meout??!?!?!?!?!?A satellite operates at an altitude of 20,200 km and uses communication frequencies of1575.42 MHz. Find the gravitationalfrequency change with respect to Earth.
The solution is .834 Hz but I keep getting this wrong,please help. Will rate lifesaver!! A satellite operates at an altitude of 20,200 km and uses communication frequencies of1575.42 MHz. Find the gravitationalfrequency change with respect to Earth.

Explanation / Answer
Maybe you didn't add the altitude to the Earth radius? Treat the photon as having "mass" hf/c2 ; its change in Energy should be -mGM/R +mGM/(R+altitude) . The change in energy shows up as h f . f = (f/c2)GM(1/6.378E6 - 1/26.578E6) f = (f/c2)GM(1/6.378E6 - 1/26.578E6) I get 0.8348 , which should round up to 0.835 ...Related Questions
