A symmetric doule convex lens is cut in two equal parts by a plane perpendiculr to the pricipal axis. If the power of the original lens was 4D, the power of a cut lens will be

A symmetric doule convex lens is cut in two equal parts by a plane perpendiculr to the pricipal axis. If the power of the original lens was 4D, the power of a cut lens will be

There is a symmetric bi-convex lens and it is cut in two equal parts by a plane passing through the centre of lens and perpendicular to its principal axis. If power of original lens is 10 D then what will be the power of each part of the lens ?

An unsymmeterical double convex thin lens forms the image of a point object on its axis. Will the position of the image change if the lens is reversed ?

There is symmetric bi-convex lens and it is cut in two pieces by a plane containing principal axis. If power of the original lens is 10 D then what will be the power of each part ?
