Doppler Shift for Sound and Light (1474 words) |
 | in a material medium the Doppler frequency shift depends on whether the emitter or the absorber is moving relative to the fixed medium. |
| More generally, we can give the Doppler shift for the case when the (inertial) motions of the emitter and absorber are at any specified angles relative to the "line of sight". |
| This differs in appearance from the Doppler shift equation given in Einstein’s 1905 paper, but only because, in Einstein’s equation, the angle f is evaluated with respect to the emitter’s rest frame, whereas in our equation the angle is evaluated with respect to the absorber’s rest frame. |
