Retrieved 14 July However, since the nuclear wave functions for different M J have different orientations in space relative to the magnetic field, any orientation dependence, whether from an aether wind or from a dependence on the large-scale distribution of mass in space see Mach's principlewould perturb the energy spacings between the four levels, resulting in an anomalous broadening or splitting of the line. Michelson—Morley type experiments have been repeated many times with steadily increasing sensitivity. A mist of atomized oil drops was introduced through a small hole in the top plate and was ionized by an x-raymaking them negatively charged. Although the estimated difference between these two times is exceedingly small, Michelson and Morley performed an experiment involving interference in which this difference should have been clearly detectable.

  • The Michelson–Morley experiment was an attempt to detect the existence of aether, a supposed medium permeating space that was thought to be the carrier of.

    The Michelson–Morley experiment was a scientific experiment to find the presence and properties of a substance called aether, a substance believed to fill. The oil drop experiment was performed by Robert A. Millikan and Harvey Fletcher in to measure the elementary electric charge The experiment took place.
    Ordinary oil would evaporate under the heat of the light source causing the mass of the oil drop to change over the course of the experiment.

    Albert Einstein formulated the theory of special relativity byderiving the Lorentz transformation and thus length contraction and time dilation from the relativity postulate and the constancy of the speed of light, thus removing the ad hoc character from the contraction hypothesis. Once again, no effect was seen, so aether-drag theories are considered to be disproven.

    In the same way, aether should seem like a moving substance to things on Earth. Michelson's apparatus was subject to experimental errors far too large to say anything conclusive about the aether wind.

    These include experiments from toand a series of experiments in the s. This hypothesis was partly motivated by Oliver Heaviside 's discovery inthat electrostatic fields are contracting in the line of motion. Here the contraction of moving bodies follows from the two fundamental principles of the theory, without the introduction of particular hypotheses; and as the prime factor involved in this contraction we find, not the motion in itself, to which we cannot attach any meaning, but the motion with respect to the body of reference chosen in the particular case in point.

    This pattern is due to the yellow sodium D line being actually a doublet, the individual lines of which have a limited coherence length. The frequency of a rotating microwave cavity resonator is compared with that of a quartz clock.

    Einstein emphasized the kinematic foundation of the theory and the modification of the notion of space and time, with the stationary aether no longer playing any role in his theory.
