Draw a ray diagram showing how a concave mirror can be used to produce a real, inverted and diminished image of an object.

Describe with the help of a diagram, the nature, size and position of the image formed when an object is placed beyond the centre of curvature of a concave mirror.

If an object is placed at a distance of 8 cm from a concave mirror of focal length 10 cm, discuss the nature of the image formed by drawing the ray diagram.

Which mirror is used as a torch reflector ? Draw a labelled diagram to show how a torch reflector can be used to produce a parallel beam of light. Where is the bulb placed in relation to the torch reflector?

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.
