Although in this case the waves are not in the visible spectrum, physicists still call the stretching and shrinking of the waves red-shift and blueshift, respectively.
In addition, the speed at which an object such as a star or galaxy is moving away from Earth, because of the expansion of the universe, can be worked out from its red-shift.
