Question

Ratio of height of the image to the height of the object is called the ___ of the spherical mirror.

• A. radius of curvature
• B. focus
• C. magnification
• D. focal length

Answer 1

The correct option is C magnification

Magnification produced by a spherical mirror is defined as the ratio of the height of the image to the height of the object. It can also be defined as the ratio of the image distance $\left(v\right)$ to the object distance $\left(u\right)$.
$\frac{h^{\prime }}{h}=\frac{-v}{u}$
