(5) Silvering of One of the Surface of a Lens (a) Focal Length of Plano-Convex Lens when Its Plane Surface is Silvered In this case the rays coming from the object first get refracted from the convex surface and then get reflected from the polished place surface and again refracts out from convex surface. If f and f be the focal length of the lens (convex surface) and mirror (plane polish surface) respectively then effective focal length of the lens F is given by m 1) can't understand the derivation. explain me.
