When an object is placed between the focus and the pole of a concave mirror, the image formed is

Options

A. real, inverted and small
B. real, inverted and same size
C. real, inverted and enlarged
D. virtual, erect and enlarged

Answer

To determine the nature of the image formed when an object is placed between the focus and the pole of a concave mirror, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Components of the Concave Mirror**:
- A concave mirror has a pole (P), a focus (F), and a center of curvature (C).
- The focus is located between the pole and the center of curvature.

2. **Position the Object**:
- Place the object between the focus (F) and the pole (P) of the concave mirror.

3. **Draw Ray Diagrams**:
- Draw a ray parallel to the principal axis from the top of the object. This ray will reflect off the mirror and pass through the focus (F).
- Draw another ray that passes through the center of curvature (C). This ray will reflect back along its path.

4. **Extend the Reflected Rays**:
- Since the rays do not actually converge in front of the mirror, extend the reflected rays backward. The point where the extended rays appear to diverge from is where the virtual image is formed.

5. **Determine the Characteristics of the Image**:
- **Nature of the Image**: The image is virtual because the rays do not actually meet; they only appear to diverge from a point behind the mirror.
- **Orientation of the Image**: The image is erect (upright) because it is above the principal axis.
- **Size of the Image**: The image is enlarged compared to the object since it is formed between the focus and the pole.

6. **Conclusion**:
- The image formed when the object is placed between the focus and the pole of a concave mirror is virtual, erect, and enlarged.

### Final Answer:
The image formed is **virtual, erect, and enlarged**.
