  The Compton effect is commonly cited as a demonstration of the particle
feature of light, while the wave nature of matter has been proposed by de
Broglie and demonstrated by Davisson and Germer with the Bragg diffraction of
electron beams. In this investigation, we present an entirely different
interpretation of the Compton effect based on the postulates of de Broglie and
on an interaction between electromagnetic and matter waves. The speeds of
interacting electrons in the Compton scattering are quite fast and its
mechanism relies heavily on the mass variation. Thus, based on this wave
interpretation, the Compton effect can be viewed as a further demonstration of
the postulates of de Broglie for high-speed particles. In addition to the
scattered wave, a direct radiation depending on the mass variation is
predicted, which provides a means to test the wave interpretation.
