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

Options

A. real and inverted
B. real and enlarged
C. virtual and diminished
D. virtual and enlarged

Answer

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

### Step-by-Step Solution:

1. **Understand the Setup**:
- We have a concave mirror with a focal point (F) and a pole (P). The object is placed between the pole and the focus, closer to the mirror.

2. **Draw the Ray Diagram**:
- Start by drawing the principal axis, the concave mirror, and marking the focal point (F) and pole (P).
- Place the object (O) between P and F.

3. **Trace the Rays**:
- **Ray 1**: Draw a ray from the top of the object parallel to the principal axis. When this ray hits the mirror, it reflects through the focal point (F).
- **Ray 2**: Draw another ray from the top of the object that goes through the focal point (F) before hitting the mirror. This ray will reflect back parallel to the principal axis.

4. **Extend the Reflected Rays**:
- The reflected rays do not meet on the same side of the mirror. Therefore, extend these rays backward (in the direction opposite to the incoming rays) to find the point where they appear to diverge from.

5. **Locate the Image**:
- The point where the extended rays appear to diverge is where the virtual image (I) is formed. This image is located behind the mirror.

6. **Determine the Properties of the Image**:
- **Virtual**: The image cannot be projected on a screen as it is formed by the extension of reflected rays.
- **Erect**: The image maintains the same orientation as the object.
- **Magnified**: The size of the image is larger than the size of the object.

### Conclusion:
When an object is held between the pole and the focus of a concave mirror, the image formed is virtual, erect, and magnified.
