A thin Plano convex lens (μ = 5/4) fits exactly into a Plano concave lens μ = 3/2. The radius of curvature of the curved interface is 30 cm.
(1) If plane surface of Plano convex lens is silvered, then the
(a) System behaves like a concave mirror
(b) System behaves like a convex mirror
(c) Focal length of the system is 45 cm
(d) Focal length of the system is 60 cm
(2) An object of height 5 cm is placed at a distance of 15 cm from equivalent mirror of the previous problem. Then transverse magnification produced by the system is.
(a) -4/5
(b) + 4/5
(c) -5/4
(d) +5/4
