Question

State the relation between object distance, image distance and focal length of a spherical mirror.

Answer 1

1. The relation between object distance, image distance and focal length of a spherical mirror is given as,

$\frac{1}{f}=\frac{1}{u}+\frac{1}{v}$

Where $f$ is the focal length of the mirror, $u$is the distance between the object and focus of the mirror, $v$is the distance between the image and focus of the mirror.

2. The above formula is called the mirror formula.
