Classical waves and the Doppler shift

[QUOTE="jartsa, post: 6005470, member: 386340"] Think carefully about what the moving observer thinks, he does not necessarily think the wavelength has changed. Or read below: When a sound source moves relative to the medium, then there is a Doppler-shift of the frequency and a Doppler-shift of the wavelength. When an observer moves relative to the medium, then there is a Doppler-shift of frequency but no Doppler-shift of wavelength, according to the observer. (Wave-train is moving past me extra fast, that is why extra many wave-crests are passing me each second, says the observer) (If anyone were to look inside the ear of an observer that is moving towards a sound source, he would find there a wave with a 'shortened' wavelength. But that is not the subject now, right?) [/QUOTE]
