Abstract:
The paper considers Michelson-Morley experiment where light from a source was transmitted and reflected in two perpendicular arms of same length L, moving with velocity v. Using an interferometer, no difference was detected in the times taken for the transmitted and reflected rays to cover the length 2L in the longitudinal and transverse directions. The theory of special relativity explained the null result through conceptions of length contraction, by sqrt(1 – v^2/c^2) in the longitudinal arm, and time dilation in the transverse arm, by Lorentz factor 1/{sqrt(1 – v^2/c^2)}, where c is the speed of light in a vacuum. This makes the times taken, for the round trips of length 2L, in both arms, to be equal as 2L/c{sqrt(1 – v^2/c^2)}. This paper argues that with no relative motion between the apparatus and the observer, result of the experiment should always be a null.
