Abstract

Figure 163 represents light travelling from a point object O, on the principal axis of a lens, to form a real image at I. The dotted curves show the positions of two wavefronts, one (AA’) diverging from O which has just reached the lens surface at A, and the second (BB’) converging to I, having just left the second surface of the lens at B.
