For and , calculate the path difference between longitudinal and lateral... · PHYSICS Dataset #7382

The Michelson-Morley experiment tests whether light travels at different speeds along and perpendicular to Earth's motion through the "ether." The key insight is that if the ether exists, the two perpendicular light paths should take different times to return, creating a measurable path difference. You'll use the time-delay formulas for each arm (accounting for the velocity $v$ of Earth's motion) to find how many wavelengths this difference spans—the fringe shift that would reveal the ether's presence.
