Step-by-step explanation:
To find : Magnification of the image.
Solution :
Given that,
Height of object is 3 cm.
Height of image is 6 cm.
In front of a concave mirror.
We know,
Magnification produced by a mirror is equal to the ratio of the height of the image to the height of the object.
Mathematically,
• m = h'/h
[Where, h' is height of image and h is height of object]
Put h' and h in formula :
\implies⟹ m = 6/3
\implies⟹ m = 2
Therefore,
Magnification is +2.
