Kip Thorne: "If you move toward the [light] source, you see the wavelength =
shortened but you don't see the speed changed" https://youtu.be/mvdlN4H4T54=
?t=3D296

Professor Martin White, UC Berkeley: "...the sound waves have a fixed wavel=
ength (distance between two crests or two troughs) only if you're not movin=
g relative to the source of the sound. If you are moving away from the sour=
ce (or equivalently it is receding from you) then each crest will take a li=
ttle longer to reach you, and so you'll perceive a longer wavelength. Simil=
arly if you're approaching the source, then you'll be meeting each crest a =
little earlier, and so you'll perceive a shorter wavelength. [...] The same=
 principle applies for light as well as for sound. In detail the amount of =
shift depends a little differently on the speed, since we have to do the ca=
lculation in the context of special relativity. But in general it's just th=
e same: if you're approaching a light source you see shorter wavelengths (a=
 blue-shift), while if you're moving away you see longer wavelengths (a red=
-shift)." http://w.astro.berkeley.edu/~mwhite/darkmatter/dopplershift.html

The motion of the observer changes neither the wavelength of sound nor the =
wavelength of light:

"Thus, the moving observer sees a wave possessing the same wavelength [...]=
 but a different frequency [...] to that seen by the stationary observer." =
http://farside.ph.utexas.edu/teaching/315/Waveshtml/node41.html

"The wavelength is staying the same in this case." https://www.youtube.com/=

"Vo is the velocity of an observer moving towards the source. This velocity=
 is independent of the motion of the source. Hence, the velocity of waves r=
elative to the observer is c + Vo. [...] The motion of an observer does not=
 alter the wavelength. The increase in frequency is a result of the observe=
r encountering more wavelengths in a given time." http://a-levelphysicstuto=
r.com/wav-doppler.php

Accordingly, if the speed of the observer relative to the light source is V=
o, the speed of the light relative to the observer is c'=3Dc+Vo, in violati=
on of Einstein's relativity.
