2a. Where should an object be placed if you want to form an image at the focus of a convex
mirror? Use mirror formula to figure out your answer.
2b. When an object is placed at a certain distance from a concave mirror of focal length f= 20.0
cm, it produces a real image of diminished size (one half of the size of object) and now the object
is moved towards the mirror until it forms a virtual image of twice the size of the object.
(a) Find the distance between two positions of the object?
(b) Draw ray diagrams for forming images for both positions.
