A mirror produces magnified erect image of an object. The nature of the mirror is

Options

A. convex
B. concave
C. plane
D. any of the above

Answer

To determine the nature of the mirror that produces a magnified erect image of an object, we can analyze the characteristics of different types of mirrors. Here’s a step-by-step solution:

### Step-by-Step Solution:

1. **Understanding Image Formation**:
- We need to identify the type of mirror that can create an erect and magnified image.

2. **Analyzing Convex Mirror**:
- A convex mirror always produces a virtual image that is erect but diminished (smaller than the object).
- Therefore, a convex mirror cannot be the answer since it does not produce a magnified image.

3. **Analyzing Concave Mirror**:
- A concave mirror can produce different types of images depending on the position of the object.
- If the object is placed between the pole (P) and the focus (F) of the concave mirror, the image formed is virtual, erect, and magnified.
- This satisfies both conditions of being erect and magnified.

4. **Analyzing Plane Mirror**:
- A plane mirror produces an image that is the same size as the object (not magnified) and erect.
- Thus, a plane mirror cannot be the answer since it does not produce a magnified image.

5. **Conclusion**:
- The only type of mirror that produces a magnified erect image is a concave mirror. Therefore, the answer is a concave mirror.

### Final Answer:
The nature of the mirror is a **concave mirror**.
