Does wavelength change for a moving observer ?
Relative scientists claim that it does not change and that is why my demonstration of light speed invariance in classical phyiscs is wrong. Here is what ChatGPT/Copilot says: Does the observed wavelength change for a moving observer ? Yes — the observed wavelength does change for a moving observer. This is the essence of the Doppler effect . Let’s break it down carefully: 🚦 Classical (Sound Waves in a Medium) If the observer moves toward the source , the waves are encountered more frequently → shorter observed wavelength and higher frequency . If the observer moves away from the source , the waves are encountered less frequently → longer observed wavelength and lower frequency . Formula (for sound in a medium with speed v ): f ′ = f ⋅ v ± v o v where: f ′ = observed frequency f = source frequency v = wave speed in medium v o = observer speed (positive if moving toward source) Since wavelength is λ = v / f , the observed wavelength changes accordingly. https://copilot.microsof...
