"The Doppler effect - changes in frequencies when sources or observers are in motion - is familiar to anyone who has stood at the roadside and watched (and listened) to the cars go by. It applies to all types of wave, not just sound. (...) Moving Observer. Now suppose the source is fixed but the observer is moving towards the source, with speed v. In time t, ct/λ waves pass a fixed point. A moving point adds another vt/λ. So f'=(c+v)/λ."
That is, for all types of wave, the speed of the waves relative to the fixed point (observer) is
(ct/λ)(λ/t) = c
The speed of the waves relative to the moving point (observer) is
(ct/λ + vt/λ)(λ/t) = c + v,
in violation of Einstein's relativity.
