Michelson's ingenious echelon grating constitutes a realization in an unexpected manner of what was thought to be impracticable.
Michelson's experiments therefore argue in favour of the view that the luminescence in a vacuum tube is similar to that produced by phosphorescence where the translatory energy does not correspond to the oscillatory energy - but further experiments are desirable.
We have first the Doppler effect, which, according to Michelson's experiment, is the chief cause of the limit at very low pressures, but it is too small to account for the widening which is now under discussion.
Michelson's group developed a loaded, unconstrained model in which to study the kinematics of ankles which were destabilized in various ways.
Michelson, in which the ray-path was wholly in air, showed that the independence extends to higher orders.
