In a theoretical wave that does not need a medium, not necessarily EM.
the speed of the wave is given by : v=fl
where f is frequency and l is lamda, wave length
suppose there is a stationary wave generator, we can easily measure f and l from any arbitrary point.
if we move towards the generator we will experience a Doppler effect, let's say, we move in such a way that we hear the frequency 2f. by doing this, the wavelength we detect become 0.5l and thus the speed is still v. so shouldn't any wave have a constant speed disregarding the frame of reference?
