Satellite travelling away from Earth

Homework Statement



If a satellite was traveling away from Earth at a constant rate of acceleration, starting at 20% speed of light, and increasing by 2% speed of light per hour until it reached 90% speed of light, sending temperature data back at intervals of one second, how would it be received on Earth?

While accelerating, would it be received on every second? Or would their be an additional delay between each pulse because of the acceleration and velocity? What happens when the satellite reaches a constant speed?


Homework Equations





The Attempt at a Solution



If a train is coming towards you, the sound waves are closer together than if the train was speeding away from you. I don't know if this can also be observed with pulses of information traveling at the speed of light.

My guess is that you would have to have some additional delay to the one second pulses because of the acceleration, but I really don't know if the light behaves in the same manner.

You may want to think (or read) about relativistic Doppler.
