An arrow 2.5cm high is placed at a distance of 25 cm from a diverging mirror of focal length 20 cm. Find the nature, position and size of the image formed.

Height of object = 2.5cm

Object distance from mirror = -25cm


Focal length = -20cm


Using the mirror formula,


Image distance, v = 11.1 cm


Thus, the image is formed 11.1 cm behind the convex mirror and is Virtual and erect.


Magnification, m = v/u = 1.1 cm tall
