Question

Quizplus · Accepted Answer

As the source of the blinking light accelerates away from you, the frequency of the light waves reaching you decreases. This is because of the Doppler effect, which causes the wavelengths of the light waves to stretch out. As the distance between successive crests of the light waves increases, the frequency decreases, and the blinks appear less and less frequently.
