In this paper, the author demonstrates that calculation and interpretation of the Doppler effect for non-mechanical waves are possible by using the relativity theory. Since light also can be described as a wave, the relative motion of the source of light waves leads to a corresponding Doppler effect for light, based on results of Lorentz transformation between the frame of source and the frame of observer. The wavelength is shifted to larger values if the motion of the source is away from the observer and to smaller values if the motion is toward the observer. The Doppler effect on De Broglie waves is also discussed in detail. In the limiting case of negligible rest mass, the matter wave Doppler effect is shown to converge to a light wave effect. Therefore, the results of the research hold high reliability and validity, and play important role in helping students have profound knowledge about the applications of Doppler effect.
