An object of height 2cm is kept 2m in front of a convex lens of focal length 1m. A plane mirror is placed at 3m from the lens on its other side. Find the nature, position, and magnification of the final image that will be seen by an observer looking toward the mirror through the lens.

Explanation

To solve the problem step by step, we need to analyze the situation involving the convex lens and the plane mirror. Here’s how we can approach it:

### Step 1: Identify the parameters of the lens and object
- **Object height (h)**: 2 cm
- **Object distance from the lens (u)**: -2 m (the negative sign indicates that the object is on the same side as the incoming light)
- **Focal length of the lens (f)**: +1 m (positive for a convex lens)

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