Abstract

The view recently adopted by Lord Rayleigh that in the case of aberration we are concerned with the group-velocity instead of with the wave-velocity, makes it necessary to consider the experiment of Airy, in which he measured the angle of aberration with a telescope filled with water. A modification of Lord Rayleigh's explanation of this experiment leads to the result that the angle of aberration thus determined corresponds to an angle μ-1v/U measured in air. The same result is obtained from an analytical investigation, and a numerical calculation shows that the increase in the angle is about 1 per cent. - an amount that is probably too small to be detected.
