An arrow 2.5 cm high is placed at a distance of 25 cm from a diverging mirror of focal length 20 cm. Find the nature, position and size of the image formed.

Explanation

To solve the problem step by step, we will follow the principles of optics related to mirrors, particularly diverging mirrors.

### Step 1: Identify the given data
- Height of the object (arrow), \( h_1 = 2.5 \, \text{cm} \) (positive since it's above the axis)
- Distance of the object from the mirror, \( u = -25 \, \text{cm} \) (negative as per the sign convention)
- Focal length of the diverging mirror, \( f = -20 \, \text{cm} \) (negative for diverging mirrors)

### Step 2: Use the mirror formula to find the image distance \( v \)
