Default DOPPLER TOPPLES EINSTEIN

"Doppler effect (...) Let u be speed of source or observer (...) Doppler Shift: Moving Observer. Shift in frequency only, wavelength does not change. Speed observed = v+u (...) Observed frequency shift f'=f(1±u/v)"

The above analysis concerns all waves: v is the speed of the waves relative to the source. In the case of light waves v=c and the "speed observed" is therefore c'=f'L=c±u, in violation of special relativity (L is the wavelength). The following video clearly shows that, when the observer starts moving relative to the source, the wavelength remains unchanged but both the frequency and the speed of the light waves relative to the observer change:
