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 ...
