*****************************************************************************
I would like to thank everyone for the excellent responses to my question -
both online and offline.
It is counter-intuitive attempting to accept the fact that a frequency shift
can be observed if the speed of the wave front does not change. But so is
everything else associated with time dilation. At least I feel better
knowing that I am not the first to be slowed down by this question.
Furthermore, I will refrain from referring to red shift as a doppler shift.
I do understand that it is not quite the same thing.
Again, I truly appreciate the responses and feel that I can probably
continue studying the subject matter.
