haracterized by the sections employed. 28 SIMPLE LENSES. It is evident that the incident and final rays will retain their relativeobliquity during the rotation, so that all incident parallel rays have theircorresponding final rays in tlie resulting cone whose apex is at the focalpoint F. To further… … In the plano-convex spherical lens, Fig. 23, if we consider the refraction,at e^ of the ray ( merely with regard to the horizontal refraction, the finalray would take the direction p-li, and, if independently for the verticalrefraction, the final ray would assume the direction f^-v. Therefore,…
