Q16 of 223 Page 189

If an object is placed at a distance of 8 cm from a concave mirror of focal length 10 cm, discuss the nature of the image formed by drawing the ray diagram.


The focal length of the mirror is PF = 10 cm.


The object is placed at B such that


object distance, PB = 8 cm.


This means that the object lies between the pole and focus of the concave mirror.


The image formed is virtual, erect and magnified behind the mirror.
