How to derive the Lens Formula ?

Expert Answer
The figure above shows that formation of a real, inverted and diminished image A’B’ of the object AB placed beyond the centre of curvature at a distance u from the convex lens. Let v be the image distance.
According to Cartesian sign convention,
Object distance (OB) = -u
Image distance (OB’) = +v
Focal length (OF1 = OF2) = +f
From geometry of figure above, right angle ΔABO and ΔA’B’O are similar.
