In accordance with the formula (frequency)=(speed of light)/(wavelength), either
(A) frequency and speed of light pulses vary proportionally for the moving observer (distance between pulses is constant),
(B) frequency and distance between pulses vary inversely proportionally (speed of light is constant).
(A) is obviously true, (B) is obvious nonsense. Einstein wrestled with his conscience "over a lengthy period of time, to the point of despair" before introducing the nonsense:
John Stachel: "But this seems to be nonsense. How can it happen that the speed of light relative to an observer cannot be increased or decreased if that observer moves towards or away from a light beam? Einstein states that he wrestled with this problem
over a lengthy period of time, to the point of despair." http://www.aip.org/history/exhibits/einstein/essay-einstein-relativity.htm

Einstein's 1905 constant-speed-of-light postulate is just as obviously nonsensical as Big Brother's 2+2=5. Normally, an obvious nonsense is automatically rejected, but if the brainwashing ideology is powerful enough, the victim concludes in the end that "
they might be right":
George Orwell: "In the end the Party would announce that two and two made five, and you would have to believe it. It was inevitable that they should make that claim sooner or later: the logic of their position demanded it. Not merely the validity of
experience, but the very existence of external reality, was tacitly denied by their philosophy. The heresy of heresies was common sense. And what was terrifying was not that they would kill you for thinking otherwise, but that they might be right. For,
after all, how do we know that two and two make four? Or that the force of gravity works? Or that the past is unchangeable? If both the past and the external world exist only in the mind, and if the mind itself is controllable what then?"
