ourse after refraction. Draw A 0 passing through the optical centre.Since they are divergent after refraction, they can meet only by being pro-duced backwards to A, the virtual image of A. Similar rays drawn from B THIN LENSES 91 locate its image as B, and A B is the complete virtual erect image of… … Fig. 99. The Course of any Ray.—To construct the image of A, a point on theprincipal axis (Fig. 99), draw any line A KB, cutting the first focal plane at Kand the refracting plane at D. From K draw a line through 0 and from Ddraw DB parallel to K 0 which cuts the principal axis at B, the image of A.
