Question

If an object is placed in front of a curved mirror at a distance is 7 cm, the image distance is 13 cm. Image is formed on the same side of the mirror as the object. Find magnification.

• A. -3.8
• B. 1.85
• C. -1.85
• D. 2.3

Answer 1

The correct option is C -1.85

Object distance, $u=-7cm$
Image distance, $v=-13cm$
(Negative sign is because of they are in in the front of a mirror)
Magnification is given by:
$m=-v/u$
$m=-(-13)/(-7)$
$m=-1.85$
