(a) Ray Diagram- 


(b) Following are the characteristics of the image formed:

(1) It is virtual and erect.
(2) It is smaller than the object.

(c) Distance of the object 'u' = -10 cm
Focal length of the convex mirror is 5 cm.
We have to find the distance of the image 'v'.
Using the mirror formula, we get 







⇒`v=10/3` ⇒`v=3.3 cm ` 

Thus, the distance of the image is 3.3 cm behind the mirror.



Concept: Convex Mirror
