IMAGE FORMATION BY CONVEX MIRROR
There are only two possibilities of position of object in the case of a convex mirror, i.e. object at infinity and object between infinity and pole of a convex mirror.
Object at infinity:
When the object is at the infinity, a point sized image is formed at principal focus behind the convex mirror.
Image is highly diminished, virtual and erect.
Object between infinity and pole:
When the object is between infinity and pole of a convex mirror, a diminished, virtual and erect image is formed between pole and focus behind the mirror.
Image is diminished, virtual and erect.
|Positions and Nature of Image in Convex Mirror|
|Position of Object||Position of Image||Size of Image||Nature of Image|
|At infinity||At F, behind mirror||Highly diminished||Virtual and erect|
|Between infinity and P||Between F and P, behind mirror||Diminished||Virtual and erect|

Describe with a suitable diagram, how a convex mirror diverges a parallel beam of light rays. Mark clearly the pole, focus and centre of curvature of concave mirror in this diagram.
Draw a diagram to represent a convex mirror. On this diagram mark principal axis, principal focus F and the centre of C if the focal length of convex mirror is 3 cm.
If the image formed by a spherical mirror for all positions of the object placed in front of it is always erect and diminished, what type of mirror is it? Draw a labelled ray diagram to support your answer.
