You write: "The Doppler Effect in light describes the change in wavelength during the relative motion between a light (or in general electromagnetic radiation) source and its observer. For instance, when this source moves away from the observer, the wavelength of light increases or is redshifted. Conversely, if the source moves towards the observer, the wavelength of light decreases or is blueshifted."
This is completely wrong. The wavelength changes only in the case when the source moves relative to the medium transmitting the wave. When the observer moves relative to the medium, the wavelength does not change.
The two movements are not equivalent. For this reason, the theory of relativity is wrong.
