ye is very near the glass, the AOB AB AB magnification equals ^-, or - - ; that is, - „. But since the triangles a Oo a b AB ° AOB and AOB are similar, AB: AB = DO : CO. Now DO is the dis-tance of most distinct vision, and CO is very nearly equal to FO, the focallength of the lens. Therefore, the… … 564 On Light. [589- smaller—in other words, as the lens is more convergent; 2ndly, as theobservers distance of most distinct vision is greater. A simpler and more general definition of the measure of magnificationmay be stated thus :—Let a be the angular magnitude of the object as seenby the naked…
