Question

Magnification produced by a convex mirror is 1/3 then find the distance of the object from the mirror

Answer 1

so the distance of the object from the mirror is 3times its image distance

Answer 2

Answer:

The distance of the object from the mirror is three times of the distance of the image.

Explanation:

Given that,

Magnification $m =\dfrac{1}{3}$

Convex mirror is the diverging mirror.The magnification of the convex mirror is the ratio of the distance of the image and distance of the object .

The magnification is

$m= -\dfrac{v}{u}$

$\dfrac{1}{3}=-\dfrac{v}{u}$

The distance of the object is

$u= 3v$

Hence, The distance of the object from the mirror is three times of the distance of the image.
