Using mirror formula show that : 1.An object placed between focus and centre of curvature of a concave mirror produces a real image beyond the centre of curvature 2.for an object placed between the pole and the focus of a concave mirror, the image is always virtual and enlarged 3.a convex mirror always produces a virtual image independent of the location of the object 4.the virtual image produced by a convex mirror is always diminished in size and is located between the focus and the pole of the mirror
