Publisher's Synopsis
Excerpt from Aberration: And Some Other Problems Connected With the Electromagnetic Field; One of the Two Essays to Which the Adams Prize Was Awarded in 1899, in the University of Cambridge
In 54 - 56 will be found a comparison of the theoretical stresses of 52, 53 with observations, chie?y on liquid media, made by Quincke and others. The agreement is in all cases as close as could be expected in View of the experimental difficulties.
In Part IV. We have tried to ascertain the possibility of explaining aberration on the hypothesis that the polarisation of material media is continuous, not molecular as is assumed in Part II. 19, 20.
In 57 it is shown that the velocity of light in a medium drifting with constant velocity a through a stationary ether is increased by an amount fin (k 1)/k. In 58 in order to obtain Fresnel's coefficient we are driven to assume that under these conditions the ether is dragged by the material medium with velocity a (k the ordi nary facts of aberration are then explained 59, for the directions of rays prove to be governed by the same laws as in the theory of Lorentz.
