Target entity: Discovery of the aberration of light (1727–1728 observations)
Context triple: [James Bradley, notableWork, Discovery of the aberration of light (1727–1728 observations)]
  • A. Eddington 1919 solar eclipse expedition
    The Eddington 1919 solar eclipse expedition was a landmark astronomical observation campaign that measured the deflection of starlight by the Sun’s gravity, providing the first major empirical confirmation of Einstein’s theory of general relativity.
  • B. 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.
  • 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. Fizeau experiment
    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.
  • E. Royal Society expedition to observe the transit of Venus
    The Royal Society expedition to observe the transit of Venus was an 18th-century British scientific mission, notably including James Cook, sent to the South Pacific to make precise astronomical measurements that would help determine the scale of the solar system.
  • F. None of above. chosen
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
