Mirror Formula:

Positions of image formed in a curved mirror depend on:

1. The position of the object from the mirror, called object distance (u)
2. The image distance from the mirror (v)
3. And the focal length (f) of the mirror 

The object distance (u), image distance (v) and the focal length (f) are related by the formula:

  \( \frac{1}{u} + \frac {1}{v} = \frac{1}{f} \)

If a graph of  \( \frac{1}{u}\)is plotted
