Fig. 516.—Production of image by concave mirror. infinite number of rays leave A, fall upon the mirror, and after reflec-tion pass through some focus ; from these, any rays may be chosen.Consider a ray AE, parallel to the principal axis ; it passes, afterreflection, through F, the principal focus.… … Fig. 517.—Production of image by convex mirror. the image of A. Consider also a third ray, AP, arriving at P, whichwill be reflected so that .iAPB = _/;Pa. These three rays meet at a,.is will all (it hers, provided that the mirror is not too large a portionof the spherical surface, as discussed on…
