We wish to obtain an erect image of an object, using a concave mirror of focal length 15 cm. What should be the range of distance of the object from the mirror ? What is the nature of the image ? Is the image larger or smaller than the object ? Draw a ray diagram to show the image formation in this case.

Explanation

Range of the distance of the object= 0 to 15 cm from the pole of the mirror. Nature of the image = virtual, erect and larger than the object.
