How the presence of Huygens's ether was rejected ? Michelson Morley
The propagation of electromagnetic wave(light) was primarily was thought to be in a medium called luminoferous ather. Michelson Morley's revolutionary experimental setup disproved the theory of ether and interestingly showed the speed of light is independent of frame of reference, which was explained later by Einstein's theory of relativity and frame independent speed of light. The experiment was first performed with intension to prove ether by projecting light beams in opposite direction in moving frame of reference and obtaining the fringes due to both the beams, but the apparent shifting of fringes , which should be obtained by rotating the setup was not observed.
