Page:On the Influence of the Thickness of Air-space on Total Reflection of Electric Radiation.djvu/9

308 When radiation is absorbed by the receiver the resistance is decreased and this diminution of the resistance is found from the new balancing resistance.

All observations agreed in showing that as the thickness of air-space was gradually decreased, the transmitted component was increased, with a corresponding decrease of the reflected portion. I give below two sets of observations, in which the receiver acted better than usual. The results are to be taken more as qualitative, as no reliance can be placed on the sensibility of the receiver being absolutely uniform.

Radiator R2; distance between the sparking surfaces = 10·1 mm.
