The problem of measuring the velocity of light by signals sent in one direction, instead of the usual method, by signals sent out and back, is studied. This requires two clocks, and the necessary steps to set the two clocks are discussed. It is found desirable to distinguish between "veloc...

It has also been observed by Lord Rayleigh that the fronts of the waves reflected by the revolving mirror in Foacault’s experiment are inclined one to another, and in consequence must rotate with an angular velocity—where is the angle between two successive wave-planes of similar phase. ...
The Velocity of LightIN NATURE for April 4, 1931, M. E. J. Gheury de Bray points out that the determinations of the velocity of light made in this century seem to tend towards smaller and smaller values the more recent the time of observation.doi:10.1038/130025a0OLIN C. WILSONNature...
That is, light is crisscrossing in all directions in the room, but the light that is passing across our line of vision does not affect the light that comes to us from some object. This was once a most powerful argument against the corpuscular theory; it was used by Huygens. If light ...

IN determining the velocity of light by Fizeau's toothed wheel, the number of eclipses per second cannot be made more than about half a megacycle. Thus the method requires great distances. In two modern determinations, that of Karolus and Mittel-staedt at Leipzig in 1926, and that of ...
