In 1887, whose experiment was an attempt to find the velocity of the Earth with respect to the hypothetical luminiferous ether?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. Michelson and Morley.
They conducted the famous Michelson-Morley experiment in 1887 to detect the Earth's motion through the "ether" by comparing the speed of light in perpendicular directions. The null result provided crucial evidence against the ether theory and paved the way for Einstein’s theory of special relativity.
