(c) The Doppler shift combines two physical eFects: the time dilation of the moving source
and
the
traveltime diFerences involved in periodic emission (like a sine wave or a series of pulses) from a
traveling source to a “stationary” receiver). To isolate the purely timedilation eFect, it’s useful to
