ok this is a rly simple problem I just cant figure it out. There is a rocket traveling from earth to a space station (which are in the same reference frame). Earth sends light signals at some interval to the rocket, which then sends the signals to the space station. When I work this out I get that the rocket sees the signals coming from earth as dt*gamma apart where dt is earth's interval. The rocket then sends the signals at dt*gamma which should be received by the space station at dt*gamma*gamma intervals. I know for a fact this is wrong (and I suspect the first one might be wrong too) since when I draw a space-time diagram of this situation the space station receives the signals at the same speed that earth sends them and the rocket sends and receives at a higher interval. What am I doing wrong?
