Michelson used a rotating eight sided mirrored "wheel" to determine speed of light. In this case the mirror is rotated at a certain frequency which allows light to travel from the source, reflect off the mirrored wheel and into the observers eyes. What is the minimum frequency of rotation for this to happen if the distance from the fixed mirror to the rotating one is 35.4 km?
