An object is located 20 cm to the left of a diverging lens, having a focal length `f =-32cm.` Determine
the magnification of the image.
Given: `u = 20 cm and f =- 32 cm`

Explanation

To solve the problem of determining the magnification of the image formed by a diverging lens, we will follow these steps:

### Step 1: Identify the given values
- Object distance (u) = -20 cm (negative because the object is on the same side as the incoming light)
- Focal length (f) = -32 cm (negative for a diverging lens)

### Step 2: Use the lens formula
The lens formula is given by:
