Web29 sep. 2024 · In the derivation of any other formula for e.g. the mirror formula or magnification for mirrors or lenses etc., we use a specific case involving, usually but not necessarily, a convex lens. Thus we use the sign convention during the derivation as well as later while solving problems involving different sets of lenses or mirrors WebThe rear focal point of the first lens is coincident with the front focal point of the second lens F 2. Since the object and image rays are both parallel to the axis, the magnification of the system is constant: 2 1 h' f m hf This configuration forms the basis for refracting telescopes (Keplerian). The system magnification is negative. F 1 F 2 ... Web30 mrt. 2024 · So. Magnification = Height of Image/ Height of Object. m = h'/h. We also have another formula for magnification in lenses.
