First stated as a physical principle in 1842 by the Austrian physicist for whom it is named, it partially explains the red shift noted in receding galaxies.
First stated as a physical principle in 1842 by the Austrian physicist for whom it is named, it partially explains the red shift noted in receding galaxies. It is an apparent change in wavelength frequency in proportion to any line-of-sight velocity between an observer and the source of the wave. For ten points, what is this effect which explains why train whistles appear to grow higher pitched as they approach the observer?
