undaries being T and S beyond which is air, F is shortened to .F=30/l-33=22-5 in. On the other hand if beyond S there were oil of//=l-45, Fbecomes lengthened to F=30 x 145/1 -33=32-62 in. The crystalline lens of the eye in situ has power of about 22 ,D, in air ithas about 125 D. Here the relative… … Fig. 205. Thin Lens bounded by Different Media.—When a thin lens is bounded,say, on one side by air and on the other by some medium denser than air,since the lens is thin all the refraction is presumed to take place in the re-fracting plane, the position of which is presumed to be unaltered, but…
