Which experiment was designed to trace the motion of the earth through the 'luminiferous aether", a theoretical substance necessary for the transmission of light?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. Michelson and Morley experiment.
The experiment designed to trace the motion of the Earth through the 'luminiferous aether' was the Michelson-Morley experiment. Conducted in 1887 by Albert A. Michelson and Edward W. Morley, this experiment aimed to detect the presence of the aether, a hypothetical medium through which light was thought to propagate. The null result of the experiment, which found no variation in the speed of light due to Earth's motion, played a crucial role in leading to the development of Einstein's theory of relativity.
