2. Consider this concentric lens {both surfaces have the same center of curvature): r1=lmm t1'=3{lmm m'=l.5 ra=TIClmm 2'=Tmm {a} Compute the power of this lens, in diopters. [b] If a virtual object is located at the common center of curvature, as shown, where is the image?I What is the transverse magnication? {c} Explain how this magnification can be achieved with a lens whose power is not zero
