The linear magnification produced by a spherical mirror is +13. What is the type of mirror, and position of the object with respect to the pole of the mirror?

A
Convex mirror; anywhere between pole and infinity
B
Concave mirror; between focus and the pole
C
Concave mirror; between focus and centre of mirror
D
None of these

Solution:

produced is

+ \frac{1}{3}

, the image is virtual. It is a Convex mirror

.
Now,

m = \frac{image distance}{object distance}

= \frac{height of image}{height of object}

= \frac{h_{i}}{h_{o}}

= + \frac{1}{3}

The image produced by the convex mirror is smaller in size than the object, while the object is placed anywhere between the pole of the mirror and infinity.

The linear magnification produced by a spherical mirror is $+ \frac{1}{3}$ . What is the type of mirror, and position of the object with respect to the pole of the mirror?
