Abstract:
The study of the Doppler effect, presenting light as a wave, makes a distinction between the propagation velocity of the wave and the propagation velocity of its wavefront. This distinction applies to each theory, regardless of the hypothesis on which it is founded. The kinematics of light, which makes this distinction, shows that at emission, waves inherit the velocity of their source, making them in the inertial frame of the star as if the star were at rest in the absolute frame; The waves travel with the same speed c, wavelength λ, period T, and frequency f in any direction, and each spherical wavefront is always centered in the source. The Doppler effect of light applied in the kinematics of light yields the same result. For the classical Doppler effect explanation for light and special relativity, which considers the speed of light to be the constant c, unaware of the distinction between the propagation velocity of a wave and the propagation velocity of its wavefront, the Doppler effect gives in the inertial frame of a star waves traveling at variable speeds and wavelengths, but with the same period and frequency. Consequently, each spherical wavefront has its center at the instant of its emission, not in the source, and the waves look like sound waves.
