The focal length of a convex mirror is 40 cm. A point source of light is kept at distance 40 cm from the mirror. Find the distance of image from the mirror.

Explanation

To solve the problem step by step, we will use the mirror formula for a convex mirror. The mirror formula is given by:

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

Where:
- \( f \) is the focal length of the mirror
