For a concave mirror as u (object distance ) varies v (the image distance ) also varies. The graph between $\large\frac{1}{u}$ and $\large\frac{1}{v}$

1 Answer

as for mirror formula $\large\frac{1}{u} +\frac{1}{v} =\frac{1}{f}$
and f is constant.
The relation between $\large\frac{1}{u} $ and $ \large\frac{1}{v}$ is a linear relation.
$\therefore$ we get a straight line curve.
Hence b is the correct answer.
