Context triple: [Armand Hippolyte Louis Fizeau, knownFor, Fizeau–Foucault speed of light measurements]
  • A. Michelson rotating mirror experiments
    Michelson rotating mirror experiments were precision optical measurements conducted by Albert A. Michelson to determine the speed of light using rapidly spinning mirrors and long-distance light paths.
  • B. Fizeau experiment chosen
    The Fizeau experiment was a pioneering 19th-century physics experiment that measured the speed of light using a rotating toothed wheel and helped establish light’s finite velocity.
  • C. Foucault experiment
    The Foucault experiment is a 19th-century optical test devised by Léon Foucault to measure the speed of light with high precision using a rotating mirror apparatus.
  • D. Ives–Stilwell experiment
    The Ives–Stilwell experiment is a classic test of special relativity that measured the relativistic Doppler effect to confirm time dilation for fast-moving ions.
  • E. Eötvös experiment
    The Eötvös experiment is a classic physics test of the equivalence principle that measures whether different materials fall with the same acceleration in a gravitational field.
  • F. None of above.
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
