Use the mirror equation to show that an object placed between `f and 2f` of a concave mirror forms an image beyond `2f`.

Explanation

To show that an object placed between \( f \) and \( 2f \) of a concave mirror forms an image beyond \( 2f \), we will use the mirror equation:

\[ \frac{1}{f} = \frac{1}{v} + \frac{1}{u} \]

where:
- \( f \) is the focal length of the mirror,
...
