An object is placed at a distance of 12 cm from a convex lens of focal length 8 cm. Find :
nature of the image

Explanation

To determine the nature of the image formed by a convex lens, we can use the lens formula and the characteristics of the image formed by a convex lens.

### Step 1: Identify the given values
- Object distance (u) = -12 cm (The object distance is taken as negative in lens formula convention)
- Focal length (f) = +8 cm (The focal length of a convex lens is positive)

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