Correct Answer: Michelson-Morley's experiment
Solution : The correct option is Michelson-Morley's experiment .
The goal of the Michelson-Morley experiment was to determine how quickly the earth moved about the luminiferous aether, which was believed to be a medium that permeated space and carried light waves. Albert Michelson and Edward Morley experimented in the US in 1887. The purpose of the experiment was to measure Earth's movement by creating a race between a light blip travelling upstream and then downstream and one travelling across the stream and back.
