  1. {"Consider two raya Af' and III from the same point of an object (e.g a tree) incident on a concave micror, parallel to each other as shown in Iigg 7.12. The ineldent ray Af striking at the pole is reflected along , such that (i.en, ). Similarly the other ray is reflected along (since is normal at the point D). The reflected rays and interiect at a point which is the image of the point of the object. The point lies on the focal plane of the mirror. Similarly, the rays from other points of the object also converge in the focal plane thus forming the image along , Hence is an inverted, real and highly diminished image formed in the focal plane of the concave mirror. Thus","When object is at a far distance, image is in the focal plane of the mirmr. It is (i) Real, (ii) Inverted, and (iii) Highly diminished.","Fig. 7.32 When the object is at a far distance Case (iii) : When object is beyond the centre of curvature","In Fig. 7.33, is an object placed beyond the centre of curvature . Consider two light rays and the centre of curvature . Constati ins-ident from point of the object. A ray incident from point or tincipal axis, after reifous along"}
