Draw diagram to show how a convex mirror can be used to give a large field of view.

Draw a labelled ray diagram to show the formation of image in a convex mirror when the object is at infinity. Mark clearly the pole and focus of the mirror in the diagram.

State three characteristics of the image formed in this case.

The image formed by a spherical mirror is virtual. The mirror will be

Whatever be the position of the object, the image formed by a mirror is virtual, erect and smaller than the object. The mirror then must be :
