), PRISMS. 19 ■we find tho refraction active in the horizontal plane (i to p), and for anobliquity of the surfaces in the vertical plane 1 (Fig. (>)? the refraction isactive in the vertical plane (i^ to f^). Here, in the sense that the final rays are confined to the plane of inci-dence, we may… … Fig. 7.Prism, Base oblique; Refraction diametrically opposed. § 9. It is evident that the refraction is active in one and passive in theother plane for a medium whose surfaces are oblique in but one plane, sothat to obtain the refraction active in both fixed planes an obliquity of thesurfaces…
