Target entity: Ives–Stilwell experiment
Context triple: [Michelson–Morley experiment, relatedTo, Ives–Stilwell experiment]
  • A. Kennedy–Thorndike experiment
    The Kennedy–Thorndike experiment is a classic test of special relativity that examined the constancy of the speed of light using an interferometer with unequal arm lengths and varying laboratory velocity.
  • B. Michelson–Morley experiment
    The Michelson–Morley experiment was a landmark 1887 physics experiment that attempted to detect the Earth's motion through the hypothesized luminiferous aether and whose null result helped pave the way for Einstein's theory of special relativity.
  • C. Trouton–Noble experiment
    The Trouton–Noble experiment was an early 20th-century test of the luminiferous aether that searched for a torque on a charged capacitor in motion and, by finding no such effect, provided support for the emerging theory of special relativity.
  • D. Michelson interferometer
    The Michelson interferometer is a precision optical instrument that splits and recombines light beams to measure extremely small differences in path length, widely used in fundamental physics experiments and metrology.
  • E. Frisch–Peierls memorandum
    The Frisch–Peierls memorandum was a pivotal 1940 document by physicists Otto Frisch and Rudolf Peierls that first outlined the feasibility of a small, practical uranium-based atomic bomb, helping to catalyze British and later Allied nuclear weapons research.
  • F. None of above. chosen
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
