what are the characteristics of image formed by a concave mirror? please draw the ray-diagrams.
Formation of different types of images by a concave mirror

1.Image formed by a concave mirror when the object is placed between pole and focus of the mirror .(Object between P and F)


When an object is placed between the pole (P) and focus(F) of a concave mirror,the image formed is :
(i) behind the mirror
(ii) virtual and erect,and
larger than the object (or magnified).


2.When the object is placed at the focus of a concave mirror (Object at F)

When an object is placed at the focus of a concave mirror,the image formed is :
(i) at infinity
(ii) real and inverted, and
(iii) highly magnified,(or highly enlarged)

3.When the object is placed between focus and center of curvature (object between F and C)



When an object is placed between the focus (F) and center of curvature (C) of a concave mirror,the image formed is :
(i) beyond the center of curvature,
(ii) real and inverted, and
(iii) larger than the object (or magnified).


4.When the object is at infinity 




When an object is at infinity from a concave mirror,the image formed is :
(i) at the focus(F),
(ii)real and inverted , and
(iii) much smaller than the object (or highly diminished).


5.When the object is placed at the center of curvature of a concave mirror (Object at C)



When an object is placed at the center of curvature (C) of a concave mirror , the image formed is :P
(i) at the center of curvature (C)
(ii) real and inverted, and
(iii) same size as the object

6.When the object is beyond the center of curvature of the concave mirror (Object beyond C )



When an object is placed  beyond the center of curvature (C) of a concave mirror,the image formed is :
(i) between the focus and center of curvature,
(ii) real and inverted, and
(iii) smaller than the object (or diminished)
