Question

Quizplus · Accepted Answer

The Michelson-Morley experiment attempted to detect the existence of ether, a hypothetical medium through which light waves were thought to propagate. However, the experiment failed to detect any difference in the speed of light regardless of the orientation of the apparatus or the speed of the Earth's motion. This result contradicted the prevailing theory of ether and paved the way for Einstein's theory of relativity.
