Clearly there is an inconsistency in the way Einsteinians teach Doppler effect: there must be indistinguishability between "Moving source, stationary observer" and "Stationary source, moving observer" and yet in the former case the distance between subsequent pulses is shown to be shortened while in the latter case it is unchanged. Indistinguishability can only be achieved if the distance is unchanged in both cases, but then Einsteinians will have to admit that Einstein's 1905 light postulate is false - the speed of light (relative to the observer) varies with the speed of the source, as predicted by Newton's emission theory of light.

Einsteinians teaching that a light source which starts moving towards the observer sends, just like a sound source, SHORTER wavelength:

Stephen Hawking, "A Brief History of Time", Chapter 3: "Now imagine a source of light at a constant distance from us, such as a star, emitting waves of light at a constant wavelength. Obviously the wavelength of the waves we receive will be the same as the wavelength at which they are emitted (the gravitational field of the galaxy will not be large enough to have a significant effect). Suppose now that the source starts moving toward us. When the source emits the next wave crest it will be nearer to us, so the distance between wave crests will be smaller than when the star was stationary."

Nothing prevents us from considering the antithesis as well:

THESIS: A light source which starts moving towards the observer sends, just like a sound source, SHORTER wavelength, while the speed of the light relative to the observer remains the same.

ANTITHESIS: A light source which starts moving towards the observer sends, unlike a sound source, the SAME wavelength but FASTER light - the speed of the light relative to the observer INCREASES.

For waves other than light waves the moving source does indeed send shorter wavelength - it is the same for all observers, including one moving with the source. That is, all observers measure the wavelength to be L when the source is stationary, and then all of them measure the wavelength to be L' (LL') when the source is moving.

For light waves this is obviously not the case. For instance, an observer moving with the source measures the wavelength to be L, not L'.

Conclusion: The moving light source does not send shorter wavelength - rather, it sends faster light. When the source starts moving towards the observer with (small) speed v, the speed of the light relative to the observer shifts from c to c'=c+v (as predicted by Newton's emission theory of light), which causes the frequency measured by the observer to shift from f=c/L to f'=c'/L.

University of Texas: "Thus, the moving observer sees a wave possessing the same wavelength (...) but a different frequency (...) to that seen by the stationary observer. This phenomenon is known as the Doppler effect."

When the stationary observer starts moving with (small) speed v towards the light source, the speed of the light measured by him shifts from c to c'=c+v (in violation of Einstein's relativity), and this causes the measured frequency to shift from f=c/λ to f'=c'/λ, where λ is the wavelength. If v is small enough, then both c'=c+v and f'=c'/λ are virtually exact formulas, no matter whether the relativistic correction (time dilation) is applied or not.

Albert Einstein Institute: "The frequency of a wave-like signal - such as sound or light - depends on the movement of the sender and of the receiver. This is known as the Doppler effect. (...) Here is an animation of the receiver moving towards the source:

Moving receiver: http://www.einstein-online.info/imag...ector_blue.gif

By observing the two indicator lights, you can see for yourself that, once more, there is a blue-shift - the pulse frequency measured at the receiver is somewhat higher than the frequency with which the pulses are sent out. This time, the distances between subsequent pulses are not affected, but still there is a frequency shift: As the receiver moves towards each pulse, the time until pulse and receiver meet up is shortened. In this particular animation, which has the receiver moving towards the source at one third the speed of the pulses themselves, four pulses are received in the time it takes the source to emit three pulses."

Premise 1: "The distances between subsequent pulses are not affected, but still there is a frequency shift."

Premise 2: "Four pulses are received in the time it takes the source to emit three pulses."

Conclusion: The moving receiver (observer) measures the speed of the light pulses to be:

c' = (4/3)c

in violation of Einstein's relativity.
