    In one of the early (1881) versions of Michelson's interferometer, the arms were about 50 cm long. What would be the expected shift ΔN when he rotated the apparatus through 90^∘, assuming that λ=590  nm and that the expected speed of the earth relative to the ether was 3 ×10^4  m / s ? (In this case the expected shift was so small that no one regarded his failure to observe a shift as conclusive.) | Numerade
