Which experiment demonstrated that clocks on fast-moving aircraft run slower compared to ground clocks?.
- A.Michelson-Morley experiment
- B.Hafele–Keating experiment
- C.Muon lifetime
- D.Observation of length contraction
Model answer
What a good answer should say
- Hafele–Keating experiment
Explanation
Why this works
Evidence: Hafele–Keating experiment. Interpretation: Clocks on aircraft lagged behind ground clocks after a round trip.
Implication: Moving clocks run slower, confirming time dilation. Conclusion: The experiment provides clear evidence for time dilation.
