364773 A convex lens of focal length of \(40\,cm\) is in contact with a concave lens of focal length \(25\,cm\). The power of the combination is

364774 The following figure represents two biconvex lenses \(L_{1}\) and \(L_{2}\) having focal length \(10\,cm\) and \(15\,cm\) respectively. The distance between \(L_{1}\) and \(L_{2}\) is

364775 What should be the value of distance \(d\) so that final image is formed on the object itself. (focal lengths of the lenses are written on the lenses).

364776 How many images are formed by the lens shown, if an object is kept on its axis?

364777 An object is placed \(40 {~cm}\) away from a convex lens of focal length \(15 {~cm}\) and a sharp image is formed on a screen. Now a concave lens is placed in contact with the convex lens. The screen now has to be moved away from the lens system by \(96 {~cm}\) to get a sharp image again. What is the focal length of the concave lens ?
