Question
State the mirror formula and write it mathematically.
✓
Answer
The relationship between the object distance (u), the image distance (v) and the focal length (f) of a mirror is known as the mirror formula.
It is given by
$\frac{1}{v}+\frac{1}{u}=\frac{1}{f}$ ......(9.4)
where, u=the distance of the object from the pole of the spherical mirror
v=the distance of the image from the pole of the spherical mirror
f= the distance of the principal focus from the pole of the spherical mirror
