We notate this factor as D (which can stand for either “Doppler” or “diagonal”).

Imagine that rain is falling vertically while you drive in a convertible with the top down. To you, the raindrops appear to be moving at some nonzero angle relative to vertical. This is referred to as aberration.

(As with the earlier trip using instantaneous jumps from stillness to motion, and the reverse, the initial acceleration-induced time effects at the beginning of the trip and the final deceleration-induced time effects at the end of the trip will essentially cancel the time-dilation effects of the unaccelerated portion of the trip.)

The actual change in frequency is called the Doppler shift. A sonic boom is constructive interference of sound created by an object moving faster than sound. A sonic boom is a type of bow wake created when any wave source moves faster than the wave propagation speed.

If the observed wavelength is longer than the rest wavelength, the shift is called “redshift.” On the other hand, if the object is moving toward the observer, z will be negative, and so will the velocity.
