In an experiment to find focal length of a concave mirror, a graph is drawn between the magnitudes of $u$ and $v$ . The graph looks like

Answer:

Solution:

For a concave mirror, $\frac{1}{v} + \frac{1}{u} = \frac{1}{f}$

$v = \frac{u f}{u - f}$

As $u$ increases, $v$ decreases non-linearly: the decreasing curve (c).
