Going at a significant fraction of the speed of light, you pilot a spaceship right past a navigational beacon that is emitting a radio wave. You measure the radio wave’s frequency as you approach the beacon, and then you measure it again after you pass the beacon and are receding from it. As you pass the beacon, the frequency you measure decreases due to the Doppler effect, and the difference between the two measurements is the Doppler shift. Compared to the frequency shift that Newtonian physics would predict, the relativistic Doppler shift is:
a) smaller
b) larger
c) the same
