5) MICHELSON AND MORLEY EXPERIMENT
A- Michelson and Morley (1887)
At the time it was believe that light needed a medium to travel, it was called "ether". The
purpose of the experiment was to detect the movement of the earth through ether. Remember the
earth describe a circular orbit around the sun in one year. From the orbit radius we obtain a
tangent speed for the earth around the sun of 3 km/s. To this we have to add the earth
rotational speed .05 km/sec.
Now if you look at the drawing you see two total mirrors "B" and "C". The light in blue from the sun falls on the half mirror "A" so that the rays are split between mirror "B" and "C". In the experiment the arm "AB" "AC" of the interferometer are placed parallel or at right angle to the earth speed. Michelson than obtained something he was not expecting. He could not get a variation in the interference figure of the two light rays coming back from mirror "B" and "C". Because of the speed of the earth they should have returned to the observer with a phase shift. Later Eisntein propose that space and time will expand or contract in order to explain the result of the experiment.
