Most of us know about redshifting, a phenomenon of the Doppler effect. This is the change in frequency of a wave, both mechanical and electromagnetic, for an observer when there is relative motion between the source and the observer. For example, when an observer is moving closer to a wave source, each successive wave front […] Continue reading Continue reading
