Question

if a mirror produces a magnification of 13 . when an object is placed at a distance of 20 cm from the mirror, find the position of image

Answer 1

magnification =image distance/object distance then , magnification=13 ,object distance=20, by putting this in formula , magnification= 13 × 20=260 cm

Answer 2

Hi !

magnification = m =  13

object distance = u = -20 cm

Image distance = v = ?

m = -v/u

-v = m*u

-v = 13*-20

-v = -260

v = 260 cm

The image formed is virtual and erect 

The image is formed at a distance of 260 cm behind the mirror

The mirror is convex
