Interferometer
notes: label: Description
content: Designed by the American physicist, Albert A. Michelson, this type of interferometer measures the speed of light along two different paths. Using an instrument of this sort in 1887, Michelson and Edward Morley showed that the speed of light is not affected by the motion of the earth through the supposed luminiferous ether. This unmarked example came from the University of Illinois.
