Abstract:
Emission, propagation, and reflection of light as mechanical phenomena applied to the Michelson-Morley experiment offer a zero-fringe shift in Earth’s inertial frame. Differently, in the Majorana experiment, the light from a fixed source reflected by moving and fixed mirrors enters the Michelson interferometer with unequal arms and offers a noticeable fringe shift. According to Majorana’s interpretation, the fringe shift is proof of the constancy of light velocity. In contrast to Majorana’s conclusion, the light reflected by a moving mirror has a different speed, wavelength, and frequency from incident one, and the fringe shift observed in his experiment indicates that the velocity of light depends on its source velocity. Majorana’s derivation predicts a 0.71 fringe shift, and this study a 0.27 fringe shift.
