In the following video the observer starts moving with speed v away from the light source. One can see that the speed of the wavecrests relative to the observer shifts from c to c'=c-v and, accordingly, the frequency measured by the observer shifts from f=c/L to f'=(c-v)/L=f(1-v/c), where L is the wavelength. Yet Bingo the Einsteiniano teaches that Bingos should only see the frequency shift from f=c/L to f'=(c-v)/L while the speed of the wavecrests relative to the observer does not shift from c to c'=c-v, no it doesn't, only cranks say it does, help, help, this speed gloriously remains constant, absolutely constant, this speed does not shift at all, it never shifts, it is the same for all observers, Divine Albert said so, confirmed in countless experiments, c'=c, not c'=c-v, Divine Einstein, yes we all believe in relativity, relativity, relativity:
Now Bingo the Einsteiniano teaches that, not only for light waves but also for sound waves and why not for all waves, the wavelength varies with the speed of the observer so that the speed of the wavecrests relative to the observer gloriously remains constant, absolutely constant, Divine Einstein, yes we all believe in relativity, relativity, relativity:
In Divine Albert's world the old principle of Ignatius of Loyola is valid and Bingo the Einsteiniano obeys it:
Ignatius of Loyola: "That we may be altogether of the same mind and in conformity with the Church herself, if she shall have defined anything to be black which appears to our eyes to be white, we ought in like manner to pronounce it to be black."
