Question
What is mirror formula ? Does this formula hold good for a plane mirror ?
✓
Answer
Mirror formula is $\frac{1}{f}=\frac{2}{r}=\frac{1}{v}+\frac{1}{u}$
when $f$ is the focal length, $r$, the radius of curvature; $u$, the distance of object and $v$, the distance of image from pole of the mirror. Mirror formula holds good for all types of mirrors i.e. for plane, convex or concave.
