Make labeled ray diagrams to illustrate the formation of :

(a) a real image by a converging mirror.

(b) a virtual image by a converging mirror.

Mark clearly the pole, focus, centre of curvature and position of object in each case.

State where an object must be placed so that the image formed by a concave mirror is:

(a) erect and virtual.

(b) at infinity.

(c) the same size as the object.

With the help of a labelled ray diagram, describe how a converging mirror can be used to give an enlarged upright image of an object.

Briefly describe how you would find the focal length of a concave mirror quickly but approximately.

Which type of mirror is used in a solar furnace? Support your answer with reason.
