THE MECHANICAL UNIVERSE Name: Mai Nguyen Video 41. The Michelson-Morley Experiment Class: PHYS 2426 1. What was the Michelson-Morley experiment designed to do? Detect the motion of the earth through the luminiferous ether. 2. When was the Michelson-Morley experiment done? 1887 3. What was the ether? The substance that filled what would otherwise be space; used to nourish and illuminate the earth. 4. What does the speed of a wave depend on? The stiffness of the medium through which it passes. 5. How many light beams are used in Michelson’s interferometer? Two. 6. What sort of problems did Michelson have with his first interferometer?

Unformatted text preview: 7. How many times more sensitive was Michelsons second interferometer? 10 times 8. What did the new interferometer float on? Mercury 9. What was the surprising outcome of the Michelson-Morley experiment? There was no shift at the fringes at all, so there was no difference or delay at all. 10. What were the implications of the experiment? Failed to detect the ether, so there was none. 11. What is the principle behind relativity? The measurement of velocity of light, the measurement of diameter of star, were all related. 12. Who became the first American to win the Nobel Prize? Michaelson 13.
