Einsteinian (Both Post-Truth and Post-Sanity) Science

The motion of an observer cannot change the wavelength of any wave: it remains constant. So, in accordance with the formula

(frequency)=(speed of the wave)/(wavelength)

FREQUENCY AND SPEED OF ANY WAVE VARY PROPORTIONALLY for a moving observer.

Post-truth (post-sanity) science:

Professor Martin White, UC Berkeley: "...the sound waves have a fixed wavelength (distance between two crests or two troughs) only if you're not moving relative to the source of the sound. If you are moving away from the source (or equivalently it is receding from you) then each crest will take a little longer to reach you, and so you'll perceive a longer wavelength. Similarly 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 calculation in the context of special relativity. But in general it's just the 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/...plershift.html

If there is a next, Einstein-free version of fundamental physics, Einstein's 1905 nonsensical axiom

"The speed of light is constant"

will be replaced with the correct axiom

"For a given emitter, the wavelength of light is constant".
