Image Formation By Concave Mirrors

The object here is very far away (at infinity distance) from the Mirror and hence the Image is formed at F.
Nature Of The Image:- Real & Inverted.
Size Of The Image:- Highly Diminished, Point-Sized

The object here is beyond C and hence the Image is formed between C and F.
Nature Of The Image:- Real & Inverted.
Size Of The Image:- Diminished

The object here is at C and hence the Image formed is also at C.
Nature Of The Image:- Real & Inverted.
Size Of The Image:- Same-Sized

The object here is between C and F and hence the Image formed is beyond C.
Nature Of The Image:- Real & Inverted.
Size Of The Image:- Enlarged

The object here is at F and hence the Image is formed at infinity (as the rays do not intersect).
Nature Of The Image:- Real & Inverted.
Size Of The Image:- Highly Enlarged

The object here is between F and P and hence the Image is formed behind the mirror.
Nature Of The Image:- Virtual and Erect
Size Of The Image:- Enlarged

Image Formation By Convex Mirrors

The object here is at infinity and hence the Image is formed at F (which is behind the mirror).

Nature Of The Image:- Virtual and Erect.

Size Of The Image:- Highly Diminished, point-sized

The object here is beyond C and hence the Image formed is between F and P(behind the mirror).

Nature Of The Image:- Virtual and Erect.

Size Of The Image:- Diminished

Rays for Image Formation in Reflection

(i) A ray parallel to the Principal Axis, after reflection, will pass through the Principal Focus in case of a Concave Mirror or appear to diverge from the Principal Focus in case of a Convex Mirror.

(ii) A ray passing through the Principal Focus of a Concave Mirror or a ray which is directed towards the Principal Focus of a Convex Mirror, after reflection, will emerge parallel to the Principal Axis.

(iii) A ray passing through the Centre Of Curvature of a Concave Mirror or directed in the direction of the Centre Of Curvature of a Convex Mirror, after reflection, is reflected back along the same path.

(iv) A ray incident obliquely to the Principal Axis towards a point P on the Concave Mirror or a Convex Mirror, is reflected obliquely.

Any 2 of these rays can be used to draw Ray Diagrams and the point of intersection of the rays indicates the position of the image of the object.

Note:- All these rays follow the Law Of Reflection i.e. the Angle Of Incidence and the Angle of Reflection in all these cases will be equal.
