| Abstract: | By utilizing the transformation of time—space coordinates, the transformation of wave velocity and the Fourier transformation, this paper derivates the general expressions of Doppler effects of electromagnetic wave and elastic wave. The superposition property of elastic wave′s Doppler effect and the influence of relativistic time dilation and length contraction on elastic wave′s Doppler effect are also discussed. |
