Use the thin lens formula to show that an object placed within the focus of a convex lens produces a virtual and enlarged image.

Use the lens equation to deduce algebraically the following: "An object placed within the focus of a convex lens produces a virtual and enlarged image"

Use the mirror equation to deduce that: an object placed between the pole and focus of a concave mirror produces a virtual and enlarged image.

Use the mirror equation to deduce that: (a) an object placed between f and 2f of a concave mirror produces a real image beyond 2f. (b) a convex mirror always produces a virtual image independent of the location of the object. (c) the virtual image produced by a convex mirror is always diminished in size and is located between the focus and the pole. (d) an object placed between the pole and focus of a concave mirror produces a virtual and enlarged image.
